My science

Research interests

My research interests are in tackling complex environmental problems by combining computational hydrological models with empirical data. Merging models with data is especially interesting when they are used to study the functioning of a whole system and interlinks between different processes. Flow of water and substances in soil-water-atmosphere systems are at the core of my work. I also have a broad interest in data analytics and coding.
