Über mich
With a background in terrestrial ecology (B.S.), environmental science (M.S.) and coral reef science (PhD), I have developed expertise in a wide variety of topics, ecosystem and methods with a strong focus on quantitative ecology, spatial statistics and population ecology. I have gained work and research experience at universities, government institutions and consultancy firms and am now applying my diverse skill-set and interests to explore new avenues for creating and improving habitat for plants and animals in Zurich using blue-green infrastructure such as green roofs, urban ponds etc.
Research Focus: Quantifying the ecological performance of urban Blue Green Infrastructure using Species Distribution Models
Urban space is scarce, expensive and should thus, ideally, be multi-functional. Urban Blue-Green Infrastructure (BGI) such as green roofs, rain gardens, and urban streams and ponds may help reconcile potentially conflicting social (e.g., recreation), engineering (e.g., flood prevention and heat mitigation) and ecological needs. BGI promises to simultaneously mitigate thermal and hydrological stress while providing supplementary habitat and access to critical resources to a wide range of animal and plant species. In this project we examine how the distribution of hundreds of urban species (birds, amphibians, butterflies, dragonflies and grasshoppers) is affected by the presence of BGI in Zurich, and how the expanded deployment of BGI can remediate potential cold-spots of urban biodiversity and mitigate future impacts of climate change.
Specifically, we apply nested species distribution modelling to examine the principal drivers of the distribution of species under present and future land cover and climate conditions. To accomplish this goal we develop city-wide high-resolution maps of urban microclimatic conditions using an extensive network of urban weather stations and a range of environmental predictors including land use and remote sensing data. We further simulate likely scenarios of urbanisation for Zurich using the PLUS model, predict the impact of urbanisation on urban microclimatic conditions and examine their joint impact on the future distribution of species in Zurich under different scenarios of climate change (different shared socio-economic pathways, different general circulation models and different time periods).
