I have scholarly expertise in remote sensing, water quality, hydrology and spatiotemporal modelling.

The research stretches from measuring the water on a microscale (spectroscopic lab/field measurements) to investigating mesoscale land-water-atmosphere interactions.
The excitement of my work builds on a highly multidisciplinary approach to research, teaching and academic leadership, especially the focus on integrating multi-observation techniques with physical modelling and data-driven analysis across multiple variables and scales. 

I use the science of remote sensing, geoinformation and hydrology to investigate a variety of variables that interrelates the Earth’s systems of hydrosphere, biosphere and atmosphere.
