Research Interests
- Fluorescence methods in groundwater and contaminant tracing
- Hydrology, biogeochemistry, and general ecology of wetlands and spring creeks
- Rates, limits, and ecological effects of biological nitrogen fixation
Undergraduates: Please contact me if you would like to have 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.
Shippensburg
University M.S. program in Biology
Grads:
Please consider these or related areas for thesis work with me at Shippensburg:
- Tracing sources of organic inputs into streams and spring-creek food webs with stable isotopes (see Ecological Society of America Mid-Atlantic Poster 2007 with SU undergraduates and N. American Benthological Society Abstract 2008 with graduate student Jennifer Lentek-Klemunes)
- Determining source areas of water and sources of nutrients to spring creeks with fluorescent tracers and background tracing
- Biological assessment of spring creeks and riparian areas.
- Assessment of nutrient cycling in terrestrial, aquatic, and wetland ecosystems
There are also funds available for graduate research at Shippensburg through the Institute for Public Service
