Gregory W. Whitledge

Assistant Professor
Office: 175 Life Science II
Phone: 618-453-6089
email: gwhit@siu.edu

Education: B.S. University of Texas, Austin; M.S. University of Missouri, Columbia; Ph.D., University of Missouri, Columbia

Courses taught: ZOOL 569 (Advanced Fish Management), ZOOL 485 (Fisheries Techniques)

Areas of interest: Fish ecology and fish management

Dr. Greg Whitledge joined the SIUC Fisheries and Illinois Aquaculture Center as an Assistant Professor in 2005. Dr. Whitledge is a member of the American Fisheries Society and the North American Benthological Society. His research interests include fish bioenergetics and trophic interactions, fish-habitat relationships, application of stable isotope technology in fisheries and aquatic sciences (particularly use of otolith microchemistry and isotopic analysis for reconstructing fish environmental history), and fisheries management.

For more information on my research program, please see my lab webpage.
