Department of Physiology and Membrane Biology

Department of Physiology and Membrane Biology

Founded in 1966, the Department of Physiology and Membrane Biology is one of five basic science departments in the UC Davis School of Medicine

Our tripartite mission is to conduct innovative, cutting edge research, engage in high-level service and provide excellent educational opportunities and mentoring to students, postdoctoral fellows, and residents in the discipline of physiology. Our aim is to create new knowledge to advance understanding of biological processes and benefit society by facilitating more precise diagnosis, and effective disease treatment.

In the post molecular and post genome eras, Physiology is uniquely posed at the nexus to employ these new tools to gain a more detailed understanding of function at the molecular level or to investigate the functional consequences of alterations in gene products at the cellular, organ and organismal levels. Scientifically we are determined to access and exploit these unprecedented opportunities!




Fitz-Roy Curry, Ph.D.


Departmental faculty member Fitz-Roy Curry, Ph.D. was elected as a foreign member of the Norwegian Academy of Science and Letters in March, 2015. Dr Curry was introduced into the Academy on May 4, 2015 at the annual meeting in Oslo. He joins the Medical Sciences Group in the Division of Natural Sciences, which has 12 other foreign members worldwide. Dr Curry is recognized for his research on the microcirculation, particularly the mechanisms that regulate exchange of substances between circulating blood and the body tissues. His recent work has focused on recovery of normal function after exposure to inflammatory conditions. Dr Curry has had an active collaboration with faculty and research fellows from the Department of Biomedicine at the University of Bergen, Norway since 2005.

Dr Curry will receive the Nishimaru-Tsuchiya Award during the 10th World Congress for Microcirculation in Kyoto, Japan September 25-27, 2015. The World Congress is held every 4-5 years. There have been 6 Awards since 1984. On the occasion of the World Congress for Microcirculation, this important award is given by the Japanese Society for Microcirculation to researchers in any country with outstanding achievements in the field of microcirculation research, who have thereby greatly contributed to the development of the Japanese Society for Microcirculation. Further details of this award can be found  at




Departmental faculty member Jie Zheng, Ph.D., along with researchers from his lab, have identified the molecular interactions that allow capsaicin to activate the body’s primary receptor for sensing heat and pain, paving the way for the design of more selective and effective drugs to relieve pain. Their study appeared online June 8 in the journal Nature Chemical Biology. For more information about this exciting research, click here.


Jon Sack and Vladimir Yarov-Yarovoy labs


Departmental Faculty members Jon Sack, Ph.D. and Vladimir Yarov-Yarovoy, Ph.D. along with members of their respective labs and researchers from Lawrence Berkeley National Laboratory and the Marine Biological Laboratory in Woods Hole, Massachusetts, have a created a cellular probe that combines a tarantula toxin with a fluorescent compound to help scientists observe electrical activity in neurons and other cells. The probe binds to a voltage-activated potassium ion channel subtype, lighting up when the channel is turned off and dimming when it is activated.  For more information about this exciting research, click here.
