Education

  • BS - University of Michigan, 1978
  • DVM - Michigan State University 1982
  • Internship, Large Animal Clinical Sciences, Univ. of Tennessee, 1983
  • Residency, Large Animal Surgery, Cornell University, 1983
  • PhD in Physiology, Michigan State University, 1993
  • Postdoctoral Training in Toxicology, 1996

Teaching

  • Cardiovascular Physiology, Physiology of Blood, Mechanisms of Disease

Research Interests

My research interests include cardiovascular disease and atherosclerosis related to cigarette smoking and exposure to environmental air pollution. I am specifically interested in the mechanism by which components of cigarette smoke induce endothelial cell apoptosis.
