Research Interests
- Fluorescence methods in groundwater and contaminant tracing
- Hydrology, biogeochemistry, and general ecology of wetlands and spring creeks
- Rates, limits, cycling, and ecological effects of biological nitrogen fixation anthropogenic nutrients
Please contact me if you would like research experience in
these or related areas. The Ecology & Environmental Biology Concentration
requires 3 credits of experiential elective that may be filled with independent
research. Many students also participate in an independent research experience
regardless of concentration requirement. There are also opportunities to write your own
grants at Shippensburg to obtain supplies and travel funds, and to
at times be paid as an undergraduate research assistant. Grads,
see Shippensburg University M.S.
program in Biology for general program description, and
consider these or related areas for thesis work with me at Shippensburg. There
are also funds available for graduate research at
Shippensburg University through the Institute for Public Service.
