My goal is to mechanistically understand the soil and water dynamics and the mobility, bioavailability, and removal of nutrients and contaminants from a hydro-biogeochemical perspective. My research unravels the “magic of organic matter” and its role and interactions in biogeochemical cycles in agroecosystems.

Denitrifying Bioreactors
Woodchips denitrifying bioreactors remove nitrate from agricultural drainage. (more)
Biochar
Biochar is a product of the pyrolysis of biomass under oxygen-deprived conditions. Composed of aromatic compounds, biochar has shown the capability to remove organic compounds. (more)


Preferential flow
It is usually assumed that the wetting front in the soil is uniform. However, this is not the case. The soil has macropores and cracks through which water is transported faster than the soil matrix. (more)
Soil Carbon Cycling
To unravel how the soil microbial community uses carbon substrates under oxic and anoxic conditions, we applied 13C-glucose and tracked the assimilation of 13C in soil metabolic products. (more)


Carbon Cycling in Aquatic Environments
To unravel carbon dynamics in aquatic ecosystems, we developed a framework for carbon characterization in aquatic environments. We investigated how organic matter composition changes along a stream in an agricultural watershed (more)
