Our Team

Preserving our planet’s biodiversity is guided by knowledge of facts gained from scientific inquiry. Whether managing a forest ecosystem, restoring a disturbed habitat, or increasing the number of individuals of an endangered species, all actions are the result of dedicated people with exceptional skills who are devoting their lives to the endeavor. Without talented people there is no conservation. Here are the scientists who make up the Memphis Zoo’s Conservation and Research Team.

Dr. Elizabeth Roznik

Postdoctoral Fellow


Dr. Elizabeth Roznik is a Postdoctoral Research Fellow at the Memphis Zoo. She studies amphibian ecology and seeks to understand and mitigate the impacts of the threats that amphibians face, including habitat alteration, disease, and invasive species. Using detailed field studies and lab experiments, she investigates the behavior, ecology, and evolution of rare and common species, and makes recommendations to improve conservation efforts for these species. Her research focuses on the gopher frog (Lithobates capito) and dusky gopher frog (L. sevosus) in the Southeast US, which have both declined from habitat loss and degradation, Australian rainforest frogs that are threatened by the disease chytridiomycosis, and frogs that are negatively affected by the introduced Cuban treefrog (Osteopilus septentrionalis) in Florida.
