2014 EPP fellow at Eawag, Hussain Etemadi

January-July, 2014PhD student at Hafen City University-Hamburg / Eawag-Switzerland

During the last six months and under EPP programme, I was working on my PhD proposal that is “Sustainable and Integrated Sanitation Management in Developing Countries: The Case of Kabul’s Informal Settlements.” Meanwhile I finished my PhD application & enrollment process at my university, and started the first semester of education.

Due to ad hoc and fragmented water supply and sanitation projects in Kabul city, and attention of Afghan Government to deal with it, this is the right time to focus on sustainability and integration of sanitation planning in Kabul.

At the end I would like to express my special appreciation and thanks to my supervisor, Dr. Christoph Lüthi, for his support, Continuous guidance and encouragement.

I would also like to extend my appreciation to all Sandec members because of their warm welcome, continuous support and friendly atmosphere, and EPP committee members for providing this opportunity to increase my knowledge.


Norma Fernanda Charqueño Celis
March – May 2022
PhD student at CENAC, PNNH, CONICET/ Comahue´s University, Argentina

The main goal of my fellowship at Eawag was about a project called: “Effect of the actual warming climate trend on a shallow lake of southern Patagonia during the last ~400 yrs, with a multiproxy reconstruction”, which is part of my PhD thesis. During my stay with the Sedi-team I received an amazing training in lab work to do geochemical analyses on sediments. In three months, I was able to collect grain-size, TN/TC/TOC/TIC, biogenic Silica, C/N isotopes, biomarkers and radiocarbon data. All these results will help me to improve the reconstruction of my sediment cores and compare them to biological proxies.

But the most important part was, that I could gain experience with the analyses and discuss the results with the students of the Sedi-team. Also, this experience gave me the chance of having discussions about common problems in a PhD, e.g., issues regarding data processing in R or difficulties in writing a research article or thesis. Now I am looking forward to combining all these skills and realize a manuscript in the next months.

Additionally, I had the full support of my supervisor Nathalie Dubois, to develop a virtual conference for early career researchers called “Pre-IALIPA”, which was celebrated on April, 26-29, 2022 with almost 50 participants from all over the world. She not only gave me all the technical support to make this conference possible, but she also guided and supported me during this hard process.

Finally, even when the main goal of my fellowship was scientific, the best thing that happened to me here, was the opportunity to meet, work, and enjoy time with amazing persons who have helped me every day even with the tiniest things. All the members of the Sedi team have made me feel at home ever since day one, and they have made sure that my stay was wonderful each second, and so it was; from the lab work to the amazing trips, dinners, talks and laughs, that we shared each day of my stay. These three months were incredible because they let me grow as a scientist, but also as a person who has learnt the importance to never stop and continue learning about all the different things that this world gives to us.


2020 EPP fellow at Sandec/ESS, Christoph Lüthi / Hans-Joachim Mosler

MSc student Kh. Shafiur Rahaman
January - June, 2020

During my EPP Fellowship at the ESS/Sandec department of Eawag, I worked on a research project entitled as, ‘Psychosocial determinants of drinking chlorinated water to design behavior change interventions in Rohingya camps in Bangladesh’ under the supervision of Professor Dr. Hans-Joachim Mosler. This project was carried out in the Rohingya refugee camps in Cox’s Bazar, Bangladesh using the RANAS behavior change approach. At Eawag, I analyzed the data which has been collected previously and wrote a scientific manuscript. I learnt the advanced data analysis techniques and the ways of writing a research article according the standard of international peer-reviewed journals. With quick and continuous support from my supervisor, I was able to finish my 1st article within first 2 months and submitted it to a high rank journal. Then I started working on another similar project on Handwashing following a consultation with my supervisor.  I gained a thorough understanding of the RANAS model, data analysis and interpretation, and preparing a scientific manuscript for publication. I am really grateful to my supervisor Professor Mosler for his guidance in each steps of my work. I would like to thank Dr. Miriam Harter, who helped me a lot in data analysis and for providing necessary learning materials. I would also thank Dr. Christoph Luthi, the department head of Sandec helped me to manage the funding for publication. In a nutshell, Eawag has provided me the scientific environment to focus all my resources towards research.

2011 EPP fellow at Sandec, Supervisors: Rick Johnston, Michael Berg and Manouchehr Amini

MSc student Jannatul Ferdous
September-December, 2011

Under my EPP fellowship at Eawag, I was able to work on my MS thesis titled “Regional aquifer mapping for assessing risk of Arsenic transport of Dhaka City shallow groundwater”. During my study, I used the statistical logistic regression model for assessing the probabilities of transporting arsenic in Dhaka City groundwater. Applying the modeling system is the first time for Bangladesh where I tried to introduce a new problem of Dhaka City. Thanks to this model I obtained excellent results. For this study, I would like to thank Dr. Manouchehr Amini for his consistent guidance on modeling and for giving me the knowledge to understand the system. And I would also like to thank Dr. Micheal Berg and Dr. Rick Johnston for their help in the interpretation of the model results.

Beside my research work, I would also like to share my life experience in Switzerland: it was the first time I went far away from my family and my country. Before coming here, I didn’t cook and was depending on my family. But now I’m a self-dependent person and I can do almost everything on my own. For such an experience I am grateful to Eawag! I also feel proud to be a part of Sandec. I found all of my colleagues of the department so friendly, kind and helpful. I’ll always miss the coffee break here with all of my colleagues. They could make me feel a new family here. Finally, I would like to express my immense gratitude to EPP and Eawag for giving me such an opportunity to work with senior scientists and to complete my thesis work successfully.

2010 EPP fellow at SIAM, Prof Hans Joachim Mosler

Mohammad Mojahidul Hossain
June – August, 2010 Bangladesh project, Siam, Eawag

During my fellowship at Eawag I was working on and learning about different methods and techniques for analyzing data and interpreting the results in a comprehensive and structured manner. I learned how to write scientific articles as well as the preparation for the next phase of the ongoing arsenic related project in Bangladesh. Now I am motivated and confident myself to serve my duties with more competence in the future. I would also like to share some things of my personal life too: before I came to Switzerland I didn’t know how to cook, wash and clean, but now I am doing everything myself. Moreover, I am glad to have been able to design frameworks for the following research articles for publication in peer-reviewed journals:

  • People’s preferences and use of seven arsenic-safe drinking water options in Bangladesh (Inauen, Hossain, & Mosler)
  • Differences between stakeholders and peoples’ preferences regarding arsenic-safe water options in Bangladesh (Hossain & Inauen)
  • Perceived tastes of tubewell water and its relationship to water quality parameters (Hug, Hossain & Inauen)

Finally, I am grateful to EPP and Eawag for giving the bright opportunity and also all of my colleagues. My special thanks go to my best supervisor so far, Prof. Hans-Joachim Mosler and Jennifer Inauen for their constant guidance, assistance, stimulating discussions, advice and kind supports throughout my stay in Switzerland as well as Stephan Hug too. They helped me to have motivation in work during my stay here and of course in the future too.


Ana Clara de Sousa Matos
April - July 2023
Msc student at Federal University of Minas Gerais, Brazil

During my EPP fellowship at Eawag, I worked on the development of a hydrological model for a catchment that is used for water supply in the third biggest urban agglomeration in Brazil. Under the supervision of Dr. Fabrizio Fenicia, from the Systems Analysis, Integrated Assessment and Modelling (SIAM), I could better understand the dynamics and hydrological processes in this catchment and how they could be translated into the model. These outputs will be very helpful for the next step of my research, which aim is to optimize the reservoir located at this catchment’s outlet reducing the risk of water shortage, as part of my PhD proposal.

Besides the project that was carried out, I attended the Summer School in Environmental Systems Analysis, where I could improve my uncertainty analysis and modeling skills, in the beautiful location of Kastanienbaum, near Luzern. Also, I had the opportunity to participate in the 28th IUGG General Assembly in Berlin, where the new IAHS Scientific decade, which sets the research agenda worldwide, was launched.

In short, in these few months at Eawag, I could learn and grow in many ways, in a multicultural and very welcoming institute, where I met amazing people and built great friendships. I am grateful to the EPP Committee for this incredible opportunity. I also would like to thank Dr. Fenicia, who was a supportive and attentive supervisor, and the Hydrological Modeling group and SIAM, for the friendly work environment and all the contributions to my research.”

Tata Cathryn Ntoboh
June - September 2021
PhD student at University of Yaounde I, Cameroon

The main objective of my fellowship in Eawag was to carry out analysis on stream sediments in Douala (Economic capital of Cameroon) to assess its concentration of Heavy metals in the stream sediments of Douala river. This was a very great experience for me because I was exposed to many different aspects of the work of a sedimentologist and I was able to learn and discover new skills and methods.  During may stay here I was able to carry out different analysis in the lab such as:

  • Grain size analysis (using the sieve tower)
  • Grain size analysis by laser difractometry
  • ICP-MS  with aqua regia
  • TOC, Nitrogen and Carbon Ratio

I conducted interesting activities during my stay here at Eawag: I worked closely with the sedi team where I learned and discovered new techniques, not only in the laboratory. I went on fieldwork with some members of the team, were we collected sediments traps. I also learned how to prepare sediment cores for the XRF core scanner.

Beside my laboratory work, I had a life time experience in Switzerland: it was my first time traveling out of my country and I want to thank Eawag for giving such an interesting life opportunity. With all I have learned here I know I am a better version of myself and I see life differently. I m grateful to the Sedi team who made my stay here very comfortable and everyone was willing to teach me one thing or the other. I am looking forward to use the data I got from my analysis to write an article with the help of my supervisor Nathalie Dubois. I would like to express my gratitude first to Eawag for giving such a life changing opportunity, and giving me an opportunity to expand my scope of friendship and see the world differently.

2008 EPP fellow in Environmental Chemistry, Dr. Alfredo Alder

Tao Zhang
July - October, 2008
PhD student at Nankai University, China

During my stay at Eawag I did research on the development of a chemical analytical method for the detection of precursors of the perfluorinated compounds Perfluorooctane sulfonate (PFOS) and Perfluorooctanoic acid (PFOA) in sludge and wastewater with LC-MS/MS. The aim of the work was to establish stable instrument parameters allowing reproducible measurements. Parameter setting has been finished for the following compounds: Perfluorooctanesulfonamide (FOSA), N-methyl per-fluorooctane­- sulfonamide (N-MeFOSA), N-ethyl perfluorooctanesulfonamide (N-EtFOSA), N-methyl perfluorooctanesulfonamidoacetic acid (N-MeFOSAA), N-ethyl perfluorooctane­- sulfonamidoacetic acid (N-EtFOSAA), 8:2 Fluorotelomer unsaturated carboxylic acid (8:2 FTUCA) and 6:2 Fluorotelomer unsaturated carboxylic acid (6:2 FTUCA). Detection limits of the instrument are around 1-4 pg.

Moreover, I started an experiment on sludge sample extraction and cleanup. During my experiments, I also encountered some problems, e.g. low sensitivity on N-methyl perfluorooctane-sulfonamido ethanol (N-MeFOSE) and N-ethyl perfluorooctanesulfonamido ethanol (N-EtFOSE) with LC-MS/MS, and lab contamination on Perfluorinated carboxylic acids (PFCAs). These issues need to be solved in the future.


2008 EPP fellow in Surface Waters - Research and Management, Prof. Alfred Wüest

Fabrice Muvundja Amisi

MSc student at Makerere University, Zoology Department/Fisheries, Uganda

The aim of my fellowship at Kastanienbaum was to get first-hand training on how to write a scientific paper by using the data collected under our project: “the nutrient cycling and methane production in Lake Kivu”. During my stay at Eawag I was able to produce a paper under the supervision of Prof. Wüest and in close collaboration with many other team members. It is now ready to be submitted to an international journal for publication under the title: “Balancing Nutrient Inputs to Lake Kivu”.

I practised how to structure the literature review, to describe the methods and materials, present and discuss the results in a comprehensive and structured manner. Several commentaries during seminars also helped me to improve the discussion of the results.

This training has helped me for my future work to enhance my performance in my scientific career. No major problem was encountered throughout the work period.

Costa Rica

2017 EPP fellow at Uchem

Susana Méndez Alfaro
February to May 2017
Msc student at National University of Costa Rica, Uchem, Eawag

During my EPP fellowship at Eawag, from February to May 2017, I collaborated with the project “Pesticides Analysis in Tapezco Catchment in Zarcero, Costa Rica” in collaboration with Fredrik Weiss’ PhD at the Environmental Chemistry department. During my stay, I received training and practice in the extraction and analysis of pesticides in passive samples from SDB disks, PDMS sheets and WLP water samples. The samples were taken, in a previous collaboration of me with the project, during the sampling campaign in 2016. Moreover, I used SDB-disk extracts for 3 different eco-toxicological tests: 1. the Combined Algae Test, 2. the Yeast Estrogenic Screen Test (hERα), 3. the Bacterial Bioluminescence Inhibition Test. Additionally, I used pesticide data from 2015 from Zarcero, Costa Rica, to conduct a mixed toxicity tests with the support of the Environmental Toxicology Department.

As final results, we elaborated a standard operational procedure for the sampling and extraction of pesticides in SDB disks and for the sampling and extraction of pyrethroids and organophosphates in PDMS passive samples, with their respective short guides for use in the laboratory. Additionally, we prepared a report with the ecotoxicological data from the analysis. These documents could be used as guidelines for future research projects in Costa Rica and for other Eawag collaborators as well.    

My personal experience at Eawag was very gratifying, both personal and professional. I thank the EPP committee for the opportunity and for all the help and kindness given before, during and after my stay.

2024 EPP fellow at ESS

Mithun Raj EN
January - March 2024
PhD student at Amrita University, Amritapuri, India

During my tenure as an EPP fellow at ESS, Eawag, the Swiss Federal Institute of Aquatic Science and Technology, I was engaged in comprehensive quantitative analyses, including Multi level Path Analysis and Generalized Linear Mixed Models (GLMM), to analyze the factors explaining the adoption and regular use of the Jivamritam water purification system in Indian rural communities. This research is focused on understanding the psychological and relevant contextual determinants that contribute to the adoption of community-based water purification technologies in low- and middle-income countries (LMICs). The Jivamritam project, with its deployment in 300 diverse Indian communities, presents a unique opportunity to study the psychological determinants of this adoption.

The investigation commenced with Path Analysis to uncover the direct and indirect impacts of various factors on the rate of technology adoption. Subsequently, the application of GLMM allowed for a detailed examination of both fixed effects and random effects, thereby offering deeper insights into the drivers behind the adoption of the Jivamritam system.

The past quarter at Eawag has been an enriching period of learning and discovery. The quantitative methods applied have not only enhanced our understanding of the determinants at play but have also set the stage for targeted interventions aimed at improving water purification technology adoption and usage. The findings from this study are expected to make a significant contribution to the discourse on sustainable water management in rural environments by providing valuable perspectives that could inform future policies and implementation strategies.

I extend my heartfelt gratitude to my supervisors, Dr. Nadja Contzen and Dr. Josianne Kollmann, for their unwavering support and invaluable guidance, as well as to the stimulating academic atmosphere offered by Eawag/ESS. The journey through this project has been a pivotal phase in my Ph.D. research, broadening my analytical skills and deepening my commitment to contributing to sustainable water resource management in developing contexts.

2021 EPP Fellow at Sandec

Sudeshna Kumar
September-December 2021

Ph.D. Student, Indian Institute of Technology Kharagpur, India

During my EPP tenure at Sandec, Eawag, Swiss Federal Institute of Aquatic Science and Technology, I have developed an independent project titled "Climate Resilient Urban Sanitation Assessment Framework (CRUSAF): Hybrid analysis instrumenting geospatial mapping and scoring matrix" under the supervision of Mr. Abishek Sankara Narayan and Dr. Christoph Lüthi.

CRUSAF involves both quantitative and qualitative assessment at two levels. Firstly, conducting a geospatial analysis to assess the vulnerability of the case-specific environment. This part of the analysis will require us to generate vulnerability maps concerning climate-related hazards such as flooding, extreme heat, water scarcity and drought, and sea-level rise. Secondly, instrumentation of a scoring matrix for inspecting the resilience of the sanitation facilities.

The EPP Fellowship program has helped me diversify my research interests and encouraged me to pursue research in urban sanitation considering climate change perspectives. It has provided an immense impetus to my professional growth on an international platform which was crucial for me during the last leg of my Ph.D.

I will be forever grateful to my supervisors, Mr. Abishek Sankara Narayan and Dr. Christoph Lüthi for their continual guidance and undaunted support within and beyond academics during the entire phase of my EPP. I would also like to express my gratitude to Dr. Dorothee Spuhler for her enthusiasm and never-ending inspiration for the betterment of the project. Words are not sufficient by any means to acknowledge my EPP tenure's contribution to my thinking and my perspective towards life. I consider myself fortunate enough to be part of this fellowship program, and all the best to other EPP Fellows who I am sure shall optimize their research potential within a healthy working environment.

2019 EPP fellow at ECO, Prof. Christoph Vorburger

June - September 2019
Karthik Sankaranarayan, Ph.D student at University of Madras, India.

The EPP program supported me to work under Prof. Christoph Vorburger, Department Aquatic Ecology, Eawag. For controlling pests in agriculture, the use of insecticides has proven effective. But it has many negative consequences, especially the toxic compounds have a high possibility to discharge into nearby lakes, rivers and even ground water which will be highly detrimental to the affected ecosystems. The use of biocontrol agents (natural enemies of pests such as parasitoid wasps) is a sustainable alternative. However, this approach may be hampered if the pest is protected against natural enemies by bacterial endosymbionts. We tested this with black bean aphids (Aphis fabae), an important pest in Europe and India and one of their defensive endosymbionts, namely Hamiltonella defensa. In our experiment with different strains of this endosymbionts namely H15, H402 and H76, we tested their effect in natural condition around Eawag (6 locations; 13 rounds of replicates). The results showed that H. defensa can indeed reduce parasitism of pest aphids in the field, but the protection differed among strains, and adverse weather (heat, thunderstorms) and predators seemed to have a bigger effect on pest infestations overall than parasitism by wasps.

With the results from the experiments, we are aiming for a publication, shortly. I thank Christoph and his postdoc Nina Hafer-Hahmann, for their valuable guidance. I thank Sandec for having a wonderful program (EPP) and organizing a hike in the Swiss mountains (excursion day). Overall, this program equipped me to work in any international institute. I will always cherish the pleasant memories of Switzerland.

2018 EPP fellow in SANDEC, Dr. Linda Strande

June - September 2018
Pavan Kumar Reddy Indireddy

During my tenure I have studied on "How sanitation byproducts can improve soil quality in India". The study involved understanding current soil organic carbon status in India,  properties of Faecal Sludge (FS), organic municipal solid waste, earlier experiments on organic solids to improve soil quality and using them to arrive at reasonable estimates on amount of solids required to improve soil quality. I have used the existing scientific literature as data for my estimations. Easy access to publications through Eawag's library helped in finding potential papers a boon to the study. 

My mentor Dr.Linda Strande introduced me to a soil scientist expert who further guided in the subject of solids improving soil quality, bringing in decades of experience. Having expert support helped to arrive at reasonable assumptions and finding key papers to arrive at reliable estimates. Dr. Linda brought her expertise in estimating FS generated from the study area and in other important aspects of research like framing an outline, choosing the right journal for scientific publication.

EPP gave me an opportunity to experience well conducted research and gave an insight to what more data would be needed to make a scientific decision in choosing treatment technology or concept at an implementation level. Overall my stay in Switzerland and intercultural exposure at Sandec led to an all-round development as a sanitation professional. My gratitude to all from Eawag and Sandec for this wonderful experience. 

2010 EPP fellow in SANDEC, Ms.Elizabeth Tilley and Dr.Kai Udert

S.Ramesh Sakthivel
April-July , 2010
Ph.D Student, Indian Institute of Technology, New Delhi, India

At Eawag, under the EPP programme I carried out a study titled “Dissolution of Magnesium and Struvite Precipitation Kinetics from Stores Urine using Different Magnesium Sources”.

The study involved conducting dissolution and precipitation experiments using stored urine. Various magnesium sources including Bittern and Wood Ash were utilized for the experiments. I was also introduced to the chemical process modeling software Aquasim, software developed by Eawag, for analyzing results of the experimental data. The study outputs will be useful in designing reactors for struvite precipitation from stored urine. The work carried out will be published in an international journal and also will form a major part of my PhD thesis.

I would like to thank my supervisors, Ms.Elizebath Tilley and Dr.Kai Udert for their profound support and guidance. I take this opportunity to thank all the staff at Eawag for extending excellent cooperation to carry out the study and to the members of EPP committee for selecting me for the fellowship


2014 EPP fellow at Sandec

October 2014 - March 2015
UNESCO-IHE, Institute for Water Education

“I conducted my thesis research under the EPP programme at Eawag-SANDEC from October 2014 to March 2015. As part of an interdisciplinary research project on safe water in Nepal, I had the chance to coordinate and perform microbial water quality analyses for more than 500 households and its water sources in remote villages of Mid-Western Nepal. The research was conducted in collaboration with HELVETAS Swiss Intercooperation and further included household surveys, expert interviews and structured observations.

My research objective was the assessment of microbiological water quality and household water management practices in remote rural areas. The results revealed that most of the households` storage containers were fecally contaminated, with 21% classified as high risk cases. Also, access to safe water sources as defined by the WHO did not guarantee microbially safe water and several piped water schemes showed contamination at the tap level. The testing methodology made use of an adapted membrane filtration kit combined with a custom-made incubator powered by solar cells. It showed good performance and could be applied in similar field studies around the world.

During my research, I received a very nice mentorship from my mentors, Arnt Diener and Sara J. Marks,  and also great support from the SANDEC team. I feel that I have improved and learned a lot during my research with SANDEC.”



Ali Reza Esmaeili Ofogh

January - April 2022
PhD student at Isfahan University of Technology, Iran

During my EPP Fellowship at the Aquatic ecology department of EAWAG, benefiting from participating in Eco-seminars, I gained clear insight into critical issues that freshwater ecosystems face and the gaps in the available methods to resolve them. I also worked on my project topic. With the kind support of Dr. Christopher T. Robinson and his group members, I tried to shed light on the effect of flood intensity on the taxonomic and functional diversity of macroinvertebrate communities in understudied Karun river basin streams in Iran. During these four months, I learned how to calculate the return period of extreme flood events, which is essential in predicting floods' effect on biodiversity. Moreover, I used a disturbance-response framework to assess the effect of flood intensity on functional and taxonomic diversity indices of macroinvertebrate communities. These findings are crucial to increasing the knowledge base of conservation and management of ecological resources (e.g., ecosystem services provided by diverse macroinvertebrate communities) and biodiversity in this understudied region and biome. Such knowledge is of paramount importance, given the increasing pressures on river ecosystems and water resources due to human activities and climate change. Specifically, my stay resulted in a dataset on the taxonomic and functional composition of the studied macroinvertebrate communities. Now I am working on a draft of the manuscript on the resilience and recovery of taxonomic and functional macroinvertebrate community composition to extreme floods to publish in a high-ranking international peer-reviewed journal. In addition, I also used this chance to develop my scientific network with world-leading scientists in my research field. I will present my findings at International Mountain Conference (IMC2022) and at the 36th Congress of the International Society for Limnology (SIL2022).

I want to give my healthful gratitude to all aquatic ecology department members for providing such a warm and welcoming environment. Specifically, I appreciate the kind support of PD Dr. Christopher T. Robinson, Gabriele Consoli, and Dr. Pierre Chanut. Finally, I would like to thank all EPP committee members for providing this chance and for their kind and helpful support during the fellowship.

2015 EPP fellow

Joyce Awuor Ouma, July – October 2015, Master student at University of KwaZulu-Natal, South Africa

During my EPP fellowship at Eawag, I pioneered research on concentration of nitrified urine using reverse osmosis (RO) membranes. The objective of this research was to partially remove water from nitrified urine using RO membranes (rather than the energy intense distillation process)  and remain with a concentrated nutrient solution. Through this research,I have gained hands-on training in the scientific and operation principles of reverse osmosis membranes. In particular, their properties and performance while treating nitrified urine in terms of flux, permeability, fouling potential and cleaning mechanisms that work best.I also attended several Eawag seminars which were very enlightening and helped me to learn and improve on my presentation skills. Being an EPP fellow has given me an insight to what direction  I would like my career in water and sanitation to take.

Master student at Hanoi School of Public Health, Hanoi, Vietnam

Under my EPP fellowship at Eawag, I was able to work on my MS thesis titled “Assessing health risk due to exposure to arsenic in drinking water in Hanam Province, Vietnam”.

During my study, I used @Risk software and Environmental Health Risk Assessment method to have newer and deeper analysis on cancer risk of people using tube well water which is arsenic contaminated for drinking purpose. A draft of manuscript with new results has been written. I also used Endnote software well to build the electronic library on arsenic contamination and health risk. More importantly, I learned from my supervisor, from SANDEC members the skills (searching, document citations, issue analysis, writing skill…) and the logical, professional and very effective working style. I hope that I could apply all these things in my work in general and PhD thesis in particular in the future.

I would like to thank Rick very much for his enthusiastic, thoughtful help not only at work but also in everyday life. The SANDEC staffs were very friendly and supported me a lot. I will never forget you!

During my fellowship at Eawag from May to August 2011, I am glad to have been able to write scientific articles for my PhD research on “Health risk assessment of wastewater and excreta reuse in agriculture in Vietnam using epidemiological and quantitative microbial risk assessment methods”. The following research articles have been or will be published in peer-reviewed journals:

  • Risk factors for Entamoeba histolytica infection in an agricultural community in Hanam, Vietnam (accepted, Parasites & Vectors Journal)
  • Ascaris and Trichuris are still a health concern in Northern Vietnam when wastewater and human excreta is used in agriculture. (to be submitted)
  • Epidemiology of diarrhoeal disease related with the use of wastewater and excreta in agriculture in Hanam, Vietnam. (to be submitted)
  • Assessment of microbial infection risks of diarrhea-related to the use of wastewater and excreta in agriculture in Vietnam. (to be submitted). This paper I will be presented by poster in the BioValley ScienceDay in Basel in September 2011.

My stay at Eawag was useful for sharing and discussing research results with other Sandec colleagues working on wastewater and excreta management and also helped to facilitate the link with Swiss Tropical and Public Health Institute in Basel. At Eawag, I have been able to access many scientific papers, use the valuable facilities and to work with many friendly people. Now I am motivated and confident myself to serve my duties with more competence in the future. I would like to thank to everyone at Sandec/Eawag for all their help and support during the time I have been through.

The main objective of my three months fellowship at Eawag was the assessment of analytical data on persistent organic pollutants and heavy metals in water and sediment of Hanoi sewer system. I successfully completed two manuscripts - one has been submitted to the Journal of Environmental Pollution, and the second one is being revised by my supervisor. It can gladly say that I was one of the luckiest Vietnamese to have had the opportunity to visit Eawag under the EPP fellowship program. During my stay in Eawag, I had a good chance to learn about new research and obtain significant knowledge related to my work from experienced scientists. I was able to enhance my skills in methodology of data assessment and writing scientific papers. I had the best working conditions with the enthusiastic interest of my supervisor and laboratory staff. In my opinion, Eawag is one of the best equipped institutes that I have visited so far.


2019 EPP fellow

Ethel Mudenda
July to October 2019
PhD student at University of Zambia

During my EPP fellowship, I acquired knowledge in the management of field data, i.e. compilation, analysis and presentation particularly of farming practices in my study area.  I also enhanced my capacity in laboratory workmanship through analysis of soil samples from my study sites using state of the art equipment and following revised standard operating procedures.

EPP finances were clearly stipulated and handled; accommodation was very convenient and fully furnished; I received a warm welcome at both campuses; supervision was excellent yet minimal which taught me how to concentrate, work and provide results under minimal supervision - a positive thing I will take with me.

2009 EPP fellow in Surface Waters, Dave Senn

Jason Wamulume
March - April, 2009
MSc student, University of Zambia, School of Mines, IWRM Centre, Zambia

My work in Switzerland consisted of the following:

  • Training in laboratory analysis of water samples
  • Modelling using ArcGis and other open source resources
  • ETH course and an independent study course on wetland biogeochemistry
  • Modelling using Aquasim
  • Attending group meetings and seminars
  • Thesis structuring

During my six weeks at EAWAG I received additional laboratory training and analyzed water samples for nitrite, nitrate, ammonium, ortho- phosphate, and alkalinity. These samples consisted of reservoir and river samples from the Kafue River basin in my study area in Zambia. I also learned how to use a mass spectrometer system to analyse water samples for dissolved inorganic carbon, oxygen and hydrogen isotopes. The results from this laboratory work will form part of my thesis for a chemical balance in the study area.

I also worked at ETH-Hönggerberg and learned how to use remote sensed data in ArcGis to determine subcatchments within my study area and estimate the amount of rainfall and evapotranspiration in those subcatchment. The data sources were USGS for a DEM, flow direction and accumulation models, and FEWs remote sensed rainfall data. The hydrologic estimates will be used in my thesis for developing a water balance.

In addition, I attended a course on pollutant dynamics and modeling at ETH-Zürich once a week. My supervisor and I also had an independent study course on wetland biogeochemistry and how the links between these concepts and my research in the Lower Kafue Basin. During my last week at EAWAG I also attended a mini-course on modeling using Aquasim, a software that I may use to model some of my data.

My training and stay here were very fruitful and helpful to my studies.
