Dr. Clark received a BS in Entomology from the LSU Department of Agriculture, then a MS in Biology from UL-Lafayette. He earned his PhD from UC Irvine, Department of Ecology and Evolutionary Biology, in 1994. After postdoctoral positions at Cornell and WSU, Dr. Clark joined the faculty at IU South Bend in 1999 where he remains today. He was awarded Full Professorship in 2015 and currently serves as Chair of the Department of Biological Sciences. He teaches Human Anatomy and Physiology, Organismal Physiology, and Entomology, and has taught a course in Cannabis for the Masters of Liberal Studies program. He is first author on 16 research articles and has written two book chapters. His most recent publication, “Cannabis use is associated with a substantial reduction in premature deaths in the United States” (IUScholarworks; Aug 2017) marked his first foray into Cannabis science. It has received over 20,000 views since published. In that study, Dr. Clark used published data to estimate the impact of Cannabis use on premature deaths. This study was the first to include not only harmful effects of Cannabis, but also beneficial effects which had been overlooked in prior reviews. This study concluded that the net impact of Cannabis use is a reduction in the premature death rate of tens of thousands of deaths annually. Since that time, he has continued to focus on the health impact of moderate Cannabis use and identification of causative mechanisms underlying the beneficial impacts of moderate Cannabis use on health.
