Research topics
- I am interested in understanding how catchments function (catchment-scale hydrological and water quality processes) under natural and anthropogenic impacts (changes in land use/land cover, agricultural practices, climate) at mesoscale catchments. My current approach includes but not limited to using physically-based and machine learning models
Tool/Software
- R-SWAT: an interactive web-based R package for parallel parameter sensitivity, calibration, and uncertainty analysis with the Soil and Water Assessment Tool (SWAT and SWAT+).
- HydroEcoLSTM: a Python package with a graphical user interface (GUI) for hydro-ecological modeling using Long short-term Memory (LSTM) networks.
- SAS-N: a catchment scale model opearting at a yearly time step for simulation of nitrogen (N) transport based on the StorAge Selection (SAS) function.
- FlowStats: an R package with GUI for near-real-time streamflow statistical anaylsis for Germany
