Research Chemist
B.S. 2001 Geosciences; Ph.D. 2006 Geosciences; Penn State, Penn State
My expertise is in low-temperature aqueous geochemistry and biogeochemistry with a focus on modern terrestrial systems. With my research, I seek to discover and quantify linkages among the chemical, biological, and physical processes involved in nutrient cycling and soil formation.
