Professional Interests

Dr. Kelvin Davies joined the Einstein Department of Urology in 2001 as a basic scientist with a research background in biochemistry and molecular biology. Since 2009 he has had a joint faculty position in the Departments of Physiology and Biophysics. Overall his research applies biochemical and molecular mechanisms to understand urogenital pathology, particularly the role of smooth muscle in the development of urogenital pathology. The primary goal of these basic science studies is clinical translation and Dr. Davies’s work has resulted in the first and only FDA approved clinical trials of gene therapy to treat benign urologic disease (over-active bladder and erectile dysfunction (ED)).

At present the two major interests of his lab are the role of potassium channels in bladder and erectile function, and the role of opiorphin is erectile physiology and priapism. Collaboration with other researchers has been a hallmark of Dr. Davies’s research and he has collaborated and published with several other researchers at Einstein in such diverse areas as the use of NO-encapsulating nanoparticles for treatment of ED, peripheral nerve regeneration as a possible treatment for ED resulting from nerve damage associated with radical prostatectomy, the role of opiorphins in prostate cancer and the impact of opiorphins synthesized in the erectile tissue on systemic blood-pressure as a potential link between ED and cardiovascular disease.

His work has been funded by several grants; he has been Principal Investigator on 7 NIH grants and is currently Principal Investigator on an NIH R01 and two NY State Department of Health grants.

Research Information

In the News

BBC features research by Kelvin Davies, Ph.D., and Joel Friedman, M.D., Ph.D., that highlights using nanoparticles to treat erectile dysfunction.

The Sunday Times (UK) interviews Kelvin Davies, Ph.D., on his involvement in a study that used an innovative new drug-delivery system—nanoparticles infused with nitric oxide and applied topically---to successfully treat erectile dysfunction in animals. The nanoparticle technology was developed by Joel M. Friedman, M.D., Ph.D., professor of physiology & biophysics and of medicine at Einstein and his son, Adam Friedman, M.D., a resident in dermatology in Einstein’s department of medicine. The findings received extensive press coverage at the annual meeting of the American Urological Association on April 26, 2009.
