Purposes of this page are to attract students to courses that I teach, to attract graduate students to my lab, and to communicate research results to peers. From this page you can learn what I’m teaching, what my research interests are, what it’s like to be a graduate student in my lab, and download research publications.

Some Background: I was hired to study wetland wildlife ecology. I’m happy to work in Louisiana where wetlands are larger, more abundant, and managed/restored (not only protected) more than elsewhere. You can see my CV for details, but briefly… I worked for Bob Chabreck and earned a M.S. with a major in Wildlife from this department in 1989. I then worked for Ron D. DeLaune at LSU’s Wetland Biogeochemistry Institute from 1989 to 1994, and earned a Ph.D. in 1993 with a major in Oceanography and Coastal Sciences under the direction of William H. Patrick, Jr. In 1994, I declined a tenure-track position way up north and took a completely self-funded research position in the Biology Department at the University of Louisiana at Lafayette. In 2001, I returned to LSU as an Assistant Professor with a research/teaching split of 60/40 (the Louisiana State University Agricultural Center provides 60% of the salary whereas Louisiana State University provides 40% of the salary). In 2006, I was tenured and promoted to Associate Professor; in 2012 I was promoted to Professor.

Research Overview: My most cited papers address the response of coastal marshes to sea-level rise or petroleum pollution; my more recent papers address waterbirds, Spartina patens leaf tissue chemistry (we're basing a new wetland restoration planning technique on an old technique farmers use to plan fertilizer application), or denitrification.
