Personal and Research Interests:

I am interested in the source, transport and fate of fine sediment and associated nutrients in watersheds. In particular, I am interested in investigating the hydrological processes that link land management, erosion and sediment transport with water quality.

My specializations include:

  1. Water quality monitoring, chemistry and instrumentation.
  2. Use of naturally occurring radionuclides, laser digital relief meters and rare earth elements for the study of erosional processes.
  3. Ecosystem health assessment.

Education and Degrees:

Ph.D. University of California, Davis. Watershed Hydrology

M.S. University of Michigan, Terrestrial Ecosystem Science

B.A. Oberlin College, Biology

 

Courses Taught:
