Professor Demarest earned his B.S.
degree (magna cum laude) from
Dr. Demarest came to Juniata College in
1994, and he has served as Chair of the Biology
Department since the Spring of 1994. Previously, Dr. Demarest served as an
assistant research physiologist and lecturer at the University of California at
Berkeley, a lecturer in the Department of Zoology at the University of
California Davis; a consulting scientist at the Center for Ulcer Research and
Education at U.C.L.A.; a visiting scientist at the Marine Biological Laboratory
in Woods Hole, Mass.; a research associate in the department of medicine at the
University of North Carolina, Chapel Hill; and as a biophysicist at Bodega
Marine Laboratory.
Dr. Demarest has presented more than 30
papers at professional scientific meetings and has published more than a dozen
peer reviewed research papers, among which is a chapter in The Handbook of
Physiology published by the American Physiological Society. He has also
served as a referee for several scientific journals and as an ad hoc grant
proposal reviewer for the National Science Foundation and National Institutes
of Health.
He is a member of the American
Association for the Advancement of Science, the American Physiological Society,
the American Society of Cell Biology and the Society of General Physiologists.
Dr Demarest is a member of the Council on Undergraduate Research and serves a
Councilor for the Biology Division of CUR. Dr. Demarest is also a life member
of the Sierra Club.
His primary research interests include
cell biology and biophysics of gastrointestinal and renal epithelial transport,
as well as comparative physiology of osmoregulation
and electroreception in fish. His research and teaching have been supported by
grants from the Howard Hughes Medical Institute, National Science Foundation, National Institutes of Health, the Marine Biological
Laboratory, Smith-Klein-Beckman Foundation and the
Since he
came to Juniata, many students have performed independent research projects
with Dr. Demarest. To learn more about past and current student research in Dr.
Demarest’s lab, see the Student Research page.
