Christopher J. Davis, Ph.D., M.S.

Clinical Assistant Professor


B.A., M.S., Western Washington University
Ph.D., Washington State University

Research Interests

Dr. Davis investigates neurobehavioral and neuromolecular regulation of sleep, wake and plasticity. He employs rodent models to demonstrate the consequences of sleep loss on cognitive performance, brain chemistry and slice electrophysiology. A central focus of his work is characterizing the role of microRNAs on the electroencephalograph and vigilance states.


Dr. Davis co-teaches Mechanisms of Cell Physiology. He mentors undergraduate and graduate students from multiple disciplines.
