Parameter regionalization of hydrological models.Machine Learning and Deep learning applications in hydrology.

Visiting researcher in the Hydrogeology group of Prof. Masaki Hayashi at the Department for Geoscience

Analysis of genetic data for epidemiological studies.

Model Operations:Reviewed input parameters; ran calculation engine; validated outputs; performed sensitivity analysis on methodological approaches and changes in input parameters; supported forecast and stress testing activitiesModel enhancement:Automatized the internal model in R; rewrote the model codes to improve structure and efficiency; set up git; developed code for loading and storing data automatically on a oracle database using SQL and R; simplified usability of model for servers; standardized outputs (incl. allocation and comparison of previous period)Data analysis and visualization:Implemented data model, allowing for cross sectional review of risk measurement tools; output visualizations via Tableau, R shiny, R; automated daily loss reportingOpRisk vs. Macroeconomic factors:Investigated relationships between Macroeconomic factors and operational risk events

Lowflow Statistics:Analyzed streamflows in Europe to determine the effect of different methods for estimating lowflows. Geostatistics: GIS and R:Prepared a Europe wide data set with overlapping catchments for top-kriging; wrote R algorithms for GIS data; wrote efficient algorithms to create and further use a large data set as a directed graph (deep nested list).R packages lfstat:Helped to further develop the institutes R package by rewriting functions to improve efficiency, writing tests and update documentation.

Investigating methods for estimating trends in lowflows and floods for climate change scenarios and suggestions for future methods.

Groundwater measurements: Groundwater depth & pollution measurement campaigns over large industrial areas.Map creation after measurement campaigns: Creating maps in GIS and AutoCAD, depicting groundwater, groundwater pollution and their temporal development.
