Director of Herpetology & Restoration Ecology, Associate Research Biologist

Tiffany M. Doan is an Associate Research Biologist working at Avon Park Air Force Range to assess the synergistic effects of fire, invasive species, and grazing on the threatened and endangered herpetofauna living in upland habitats.  She received her Bachelor of Science in Biology at the University of Miami and her Ph. D. in Quantitative Biology at the University of Texas at Arlington.  She studies conservation biology, ecology, and evolutionary biology of reptiles and amphibians.  She is a founding member of the Global Assessment of Reptile Distributions working group.  In addition to scientific research, she teaches biology courses at the University of Central Florida.  She is also an avid scuba diver and scuba instructor and a practitioner of aikido martial arts.

Associate Research Biologist

My current work at Archbold includes assisting with our long-term gopher tortoise research project, monitoring seasonal scrub ponds, and managing invasive vegetation. I am also interested in wetland ecology with a focus on amphibian communities. I came to Archbold for the opportunity to work with gopher tortoises and to experience Florida’s unique ecosystems! Some of my hobbies are baking, embroidery, and gardening.

Program Information

 We combine field research, habitat restoration, and community engagement to support conservation of native reptiles and amphibians in peninsular Florida's rapidly changing landscape. Our core areas of research are:

Long-term demography and behavioral ecology of a threatened keystone species, the Gopher Tortoise (

Amphibian ecology and seasonal wetland community dynamics

Ecological restoration approaches and outcomes
