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!

Keith Baar, Ph.D. A new study suggests that consuming a gelatin supplement, plus a burst of intensive exercise, can help build ligaments, tendons and bones.

The study, from departmental faculty member Keith Baar, Ph.D. and his Functional Molecular Biology Laboratory, is published in the January issue of the American Journal of Clinical Nutrition.

Sue Bodine, Ph.D. The American Physiological Society announced that departmental faculty member Sue Bodine, Ph.D., will be the next Editor-in-Chief of the Journal of Applied Physiology. Her term begins July 1, 2017.


Aldrin Gomes, Ph.D. Departmental faculty member Aldrin Gomes, Ph.D., has been selected as 2016-2017 Chancellor's Fellow. The Chancellor's Fellows Program was established in 2000 to honor the achievements of outstanding faculty members for the quality and significance of their research and teaching.

Luis Fernando Santana, Ph.D. Voltage-gated calcium channels open in unison, rather than independently, to allow calcium ions into and activate excitable cells such as neurons and muscle cells, departmental chair and faculty member Luis Fernando Santana, Ph.D., along with researchers from his lab and the researchers from the University of Washington have found.

The research defies earlier electrophysiology canon and undermines the previously held belief that calcium channels function independently. The study is published online in the journal eLIFE.

capsaicin-molecule Humans love Sriracha sauce, and the pleasurable, painful sensation that makes us want to slather tacos, rice and barbecue with it and other spicy condiments comes down to one molecule: capsaicin. Departmental faculty members Jie Zheng, Ph.D. and Vladimir Yarov-Yarovoy, Ph.D., in collaboration with researchers in China, recently got an unprecedented, close-up view of this molecule, as well as what happens inside our bodies when we eat the spicy foods that contain it.
