Student Opportunities

We are always looking for motivated students!

Background Info and Personal Interests

We are interested in examining scientific problems from the molecular to the field scale and my research approach often requires integration of the disciplines of hydrology, geochemistry and biology with an emphasis on creating knowledge that can inform societal decision making. My students typically conduct fieldwork, develop laboratory skills and utilize numerical modeling to investigate a variety of complex biogeochemical processes and their relationship to human behavior. I have worked on problems related to water resource sustainability, surface-groundwater interaction, characterization and treatment of acid mine drainage, nutrient and carbon cycling, and subsurface and surface contaminant characterization and global climate influences on ecological function and carbon reservoirs.
