Due to forecasted winter weather, the UCO campus will be closed Wednesday, Feb. 1. All offices will be closed and all classes are canceled.
Allyson Fenwick, Ph.D.
Allyson Fenwick, Ph.D., is currently an associate professor of biology. Fenwick is a member of the Center for Wildlife Forensic Science and Conservation Studies (C-FACS). Fenwick grew up in Milwaukee, Wisconsin as the oldest of three girls. Fenwick fell in love with snakes in high school and earned her B.S. in zoology focusing on zoo and aquarium science and a B.A. in theatre from Michigan State University. After deciding zookeeping wasn’t for her, she earned an M.S. from the University of Texas at Tyler studying phylogenetics of South American pitvipers. In other words, Fenwick figures out the evolutionary relationships of snake species. Realizing she loved research and teaching, Fenwick earned a Ph.D. from the University of Central Florida in conservation biology, studying phylogenetics and the evolution of all pitvipers. She shares a home with her husband, son and daughter, and two nonvenomous snakes.

Research, Published Work, and Scholarly Activities
I am first and foremost a herpetologist and evolutionary biologist. My graduate work and ongoing interests focus on phylogenetics (evolutionary relationships of species) of pitvipers using DNA and phenotypic data. By understanding these relationships I and others can investigate interesting evolutionary patterns, such as why there are so many species in South America or if a complex character like bearing live young can evolve only in one direction or if it can reverse to an ancestral character like egg-laying.
The major focus of my lab is on population genetics of the Mediterranean gecko, Hemidactylus turcicus. This nocturnal lizard is exotic but not damaging to the environment because it is easily spread by humans and lives on building walls, eating insects. We have found that geckos at UCO show genetic differences across just a few decades and a few hundred meters. We continue to survey campus and study other independent invasions such as at the University of Oklahoma and the Oklahoma City Zoo. Several students are involved in the lab side of the project, genotyping microsatellites to analyze genetic diversity and genetic structure. Students present at Oklahoma Research Day as well as regional and national/international meetings.
Students and I have also studied the evolution of other groups, such as population genetics of fire ants at UCO and Lake Arcadia or stoneflies in the sky islands of Nevada.
