Jason Irwin

Jason Irwin is a Professor at Central Washington University, based in the Science Building (Room 338D), where he conducts research and teaching in biological sciences with a focus on organismal adaptation to extreme environments.

His academic credentials include:

• Ph.D. from Miami University, Oxford, Ohio (2000)

Dr. Irwin's research centers on physiological and ecological mechanisms of cold tolerance in freeze-tolerant insects and amphibians, investigating energy conservation strategies, water balance during freezing, and locomotor recovery post-thaw. His work bridges comparative physiology and conservation biology, examining how ectothermic species survive subzero temperatures through biochemical and behavioral adaptations. This research has critical implications for understanding climate change impacts on species distribution and extinction risks in vulnerable populations.

Analysis of his 2002-2005 publications reveals consistent investigation of cryobiological adaptations across model organisms like the goldenrod gall fly and multiple frog species. Key themes include geographic variation in freezing responses, trade-offs between energy conservation and reproductive fitness, and microenvironmental influences on overwintering survival. These studies collectively advance the fields of thermal ecology and comparative physiology through rigorous experimental approaches in both laboratory and field settings.
