Research

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

Prevalence and spread of antibiotic resistance in the environment
Lake and river water quality modeling
Hydrological catchment modeling and forecasting
Scientific software development (R, Fortran, C++)

You can find examples of current eco-hydrological models on this website maintained together with my colleage Thomas Petzoldt.

Publications

An up-to-date list of publications in peer-review journals can be found, e.g., here (google scholar) or here (ORCID).
