Melanie Langford, Ph.D.
Assistant Professor of Marine Biology
“As a passionate teacher of the natural sciences, I believe that biology is best understood by applying engaged learning techniques both in and out of the classroom. I strive to make topics exciting by studying primary literature, encouraging student presentations, and experiencing biology firsthand in a laboratory or field setting. Lastly, I strive to provide examples of research, internship, and career opportunities for my students to prepare them for careers after graduation.”
I am originally from the Midwest, and have always been interested in science in general. I have always held a great personal interest in marine biology, but also became fascinated with microbiology. I obtained my B.A. from the University of Kansas, my M.S. from the University of South Alabama, and my Ph.D. from the University of Nebraska-Lincoln before coming to FSC as an Adjunct Professor and finally as an Assistant Professor at FSC. I have a very strong background in pathogenic microbiology, and I apply that background to my current work studying the microbial flora of the manatee digestive system. My favorite part about working at FSC is that I can combine my two greatest interests: marine biology and microbiology.
I enjoy dance and the performing arts, yoga, hiking, and pretty much any ocean-related activity you can think of such as kayaking, trips to the beach, snorkeling, diving, etc.

I have worked with biology students and biology honors students on projects such as studying the bacterial composition of the manatee digestive tract. I have a collaboration with the Marine Mammal Pathobiology Laboratory (MMPL) in St. Petersburg, a facility that performs necropsies on deceased manatees, and upon obtaining a permit from the Florida Fish and Wildlife Conservation Commission, I have been able to obtain samples from these manatees for my research. I have also been able to arrange student visits to observe some of these necropsies thanks to the collaborative efforts of the wonderful researchers at the MMPL. Lastly, I am working on a project with students and my fellow biology faculty members studying the evolutionary relationship between different populations of green anoles in Florida.
