University Programs Chair, Dauphin Island Sea Lab

Senior Marine Scientist III, Dauphin Island Sea Lab

Professor of Marine and Environmental Sciences, University of South Alabama


Dr. Lee Smee is Chair of University Programs and Senior Marine Scientist III. He is a Professor of Marine and Environmental Sciences at the University of South Alabama.

Smee received his Ph.D. from Georgia Tech where he investigated how small-scale turbulence affected chemical signaling between predators and prey and influenced top-down forcing in soft sediment communities. His lab has conducted studies in rocky intertidal communities in Maine as well as oyster, marsh, and seagrass communities in the Gulf of Mexico.

Dr. Smee is an Eagle Scout and Scoutmaster of Troop 292 in Mobile, Alabama.


  • Ph.D., Georgia Institute of Technology, 2006
  • MS, Georgia Southern University, 1998
  • BS, Piedmont College, 1996



Current research topics in his lab include oyster reef ecology, mangrove encroachment, pesticide effects on blue crabs, and biogeography of seagrass communities in the Gulf of Mexico.
