Kurt J. Varner, Ph.D. Laboratory
Research interests involve determining the mechanisms by which oxidative stress produces cardiac dysfunction. There are currently 2 major areas of research interest in my laboratory.

Cardiovascular Function Core
Dr. Varner is also the director of the Cardiovascular Function Core Facility in the Department of Pharmacology. This core facility is funded in part by the COBRE grant (P20-RR018766) awarded to Daniel Kapusta, Ph.D. and Patrice Delafontaine, MD. This core facility was established to provide in vivo models to study cardiovascular function. The following techniques are routinely used in our facility.
