Research Interest

I am interested in the sources and fate of carbon in streams and rivers under different climates and hydrological extremes (droughts and floods). As hydrological extremes are occurring more frequent with climate change, there is a need to understand the impacts of these extremes on the ecological functions of streams and rivers. Especially, headwater streams are very sensitive to climatic and land-use changes and furthermore, they represent the first link between the terrestrial and the aquatic environment. Therefore, I find these small streams particularly exciting to study.

In my research, I am doing field studies and flume experiments, where I use a combination of high frequency sensors and lab analysis. With regards to lab analysis, I have focussed on spectroscopic techniques to investigate the quality of dissolved organic matter. Furthermore, I have used different techniques to estimate ecosystem metabolism in streams and experimental flumes.
