Research and publications

I'm working at the interface of hydrology, ecology, and microbiology. My focus is on process-based modeling and data analysis but I like field work and experiments as well. My research topics include:

• Prevalence and spread of antibiotic resistance in the environment
• Lake and river water quality modeling
• Hydrological catchment modeling

A recent list of publications can be found on this google scholar page or this ORCID page.
