My research interests are primarily in biogeochemistry and hydrogeology. In an effort to reduce the environmental health risks associated with natural and anthropogenic contaminants, I aim to quantitatively describe the processes governing their transport and transformation in the (sub)surface. This requires a combination of concepts from a variety of scientific fields, including geochemistry, hydrology, analytical chemistry, microbiology, environmental engineering, etc.

Currently, I am involved in a multidisciplinary, collaborative research project with the Antamina Mine in Peru, one of the world's most productive polymetallic open-pit mines. We study the processes that control the weathering and drainage of mine wastes. One research focus is quantifying the reaction- and mass transport limitations in large-scale waste rock piles (e.g., mineralogy and reactivity of the waste rock; water-, gas- and heat transport) and their controls on drainage quality; another more fundamental interest is the scalability of these processes from the porescale to industry-relevant spatiotemporal dimensions (ie. 100s of meters tall piles).

In addition, I am interested in microbial fuel cells and work on a project that examines their potential for the in-situ bioremediation of hydrocarbons in reducing aquifers.

Previously, I worked on the mass balancing of trace element fluxes in waste waters (https://pubs.acs.org/doi/abs/10.1021/acs.est.7b01731), biofilms (https://www.sciencedirect.com/science/article/pii/S0043135417310229), and the role of methylation in the biogeochemical cycling of the trace element selenium (https://www.mdpi.com/2072-6643/7/6/4199; https://www.nature.com/article...), amongst others.

I teach EOSC 429 (Groundwater contamination).
