LaTina Steele, Ph.D., is Lecturer of Biology at Sacred Heart University. 

Dr. Steele’s research interests include marine community ecology, aquatic/marine plant
chemical ecology, invasive plant ecology, and the effects of pollutants on coastal
ecosystems. Her specific research areas include: The role of chemical interactions in
determining invasion success of non-native aquatic plants. Using native herbivores to
mitigate invasive aquatic plants. Using stable isotopes to examine habitat connectivity.
Effects of the Deepwater Horizon oil spill on seagrass physiology and coastal fish
communities. Effects of habitat and predator diversity on salt marsh community structure.
The role of phenolic compounds as inducible chemical defenses against herbivory and
pathogenic infection in seagrasses. 

Degrees: Ph.D. in Marine Sciences, University of South Alabama, Mobile, AL (2010); B.S.
in Biology, University of South Alabama, Mobile, AL (2004).
