Biography

I am a Research Hydrologist with the U.S. Geological Survey, Upper Midwest Water Science Center, in the Twin Cities. I am the Team Leader for the Center’s Groundwater Characterization Team, and I am a groundwater contaminant subject matter expert on several interdisciplinary project teams. I have been working in the hydrogeology field since 1993, starting first in environmental consulting and then moving into groundwater-related research in 1998. I was a research scientist for the Minnesota Department of Health and the Minnesota Pollution Control Agency before moving to the federal government with USGS in 2009. My favorite research topic is occurrence, geochemistry, and mobilization of arsenic in natural groundwater systems. Developing models for the behavior of arsenic in the natural environment is elusive due to its complex associations with other metals and minerals, and the interplay of redox, pH, biogeochemistry, and hydrogeology. Even after 20 years of arsenic research, I continue to be fascinated.
