Gabriel Langford, Ph.D.

Professor of Biology

George W. Truitt Chair in the Sciences


I feel that using an interactive approach allows students to start asking questions about biology instead of just memorizing scientific facts, enabling them to have a broader understanding of the subject matter. I also feel strongly that ecology and environmental studies courses should be transported into an outdoor classroom whenever possible. I believe that field-based courses are the best mechanism for teaching ecology, and in my experience students excel when presented with real-world challenges.

-Gabriel Langford

Berry Citrus Science - C305




Subjects I teach include: Biology for your Life; Environmental Science; Ecology; Honors Research in Biology; Marine Biology; Biology Fundamentals; Parasitology; Evolution. More information can be found on my lab's website:

What Dr. Langford enjoys most about teaching at FSC is watching students get excited when they are exposed to new organisms and/or concepts in ecology and evolution, especially when we are in the outdoor classroom. He enjoys hiking and backpacking, camping, frogging, searching for invertebrates at the beach, SCUBA and snorkeling, biking, mountain climbing, kayaking, and loves college basketball, Rock Chalk Jayhawks!

My research focuses on the ecology and evolution of parasite life histories, and I have an interest in amphibian and reptile conservation. My research primarily occurs in and around aquatic habitats, where my students and I get wet and muddy collecting a variety of organisms! My parasitological research utilizes amphibians and reptiles as model systems to investigate issues of parasite community structure, host specificity, life cycle evolution, and biodiversity. My conservation research focuses on the population ecology of freshwater turtles in central Florida. I also have an interest in ecotoxicology and invertebrate zoology (especially spiders).
