معرفی
Dr. Fredric J Janzen is a Professor in the Department of Ecology, Evolution, and Organismal Biology at Iowa State University. His research focuses on ecology and evolution, integrating molecular genetics, quantitative genetics, and experimental field studies to examine the impacts of environmental and genetic factors on physiological, behavioral, and life-history traits in reptiles. His work emphasizes sex-determining mechanisms, early life-history variation, and population genetics with conservation applications.
Education:
- B.A., Biology, North Central College (1985)
- M.S., Zoology, Colorado State University (1987)
- Ph.D., Ecology and Evolution, University of Chicago (1992)
- Postdoctoral Fellow, Population Biology, University of California-Davis (1992–1994)
His research uses reptiles (especially turtles) to study adaptive processes, including temperature-dependent sex determination and conservation genetics. Projects include molecular phylogenetics, phylogeography, and experimental studies on predation and climate change impacts. His work is supported by multiple NSF grants (e.g., DEB-1242510, IOS-1257857).
Dr. Janzen directs the Janzen Lab, which collaborates on projects involving turtle ecology, nematode experimental evolution, and human impacts on wildlife populations. No scientific awards are explicitly listed in the provided texts.
