About Me

My main research focuses on understanding nutrients and contaminants dynamics on a molecular scale to a global level. I am currently working on two projects at Eawag : 1) understanding redox-dynamic behaviors of iron in clay minerals and 2) detection of calomel (mercurous chloride) type compounds in rocks and soils. In a project at University of Basel, I am exploring the effects of land-use-change on mercury-cycling in soils. I am keen on contributing to the field of soil and water research by linking earned skills and scientific knowledge with a strong passion for advocacy of environmental health.
