Research Interests

I am conducting basic and applied research on biogeochemical cycling of nutrients (carbon, nitrogen and phosphorus) in wetlands and aquatic systems. Work continues on developing biogeochemical indicators to evaluate changes in ecosystem function in wetlands to determine restoration success.

Student Opportunities

Graduate research assistantship (Masters) available for motivated student interested in research on wetland nutrient cycling. Please contact Dr. White by email jrwhite@lsu.edu to discuss details. Student qualifications include inorganic chemistry and strong academic background in either Geology, Biology, Chemistry, Microbiology or Environmental Science.
