Donald E. McMillan, Ph.D., Professor Emeritus
In 1978, Dr. Donald McMillan was hired as Chair of the Department of Pharmacology. Under his leadership, the department continued to increase in size and extramural research funding. In 1991, Dr. McMillan became the first basic science faculty member in the history of UAMS to receive an endowed Chair when he was named the Wilbur D. Mills Chair for Alcoholism and Drug Abuse Prevention. He established the UAMS Substance Abuse Treatment Clinic and served as its director from 1993 until his retirement in 2004. He obtained the second NIH Ph.D. training grant in the history of UAMS to support graduate and medical students in drug abuse research. During Dr. McMillan’s tenure the department rose to the top third of all medical school pharmacology departments in the country in NIH funding.
Galen Wenger, Ph.D., Professor Emeritus
Dr. Galen Wenger recently retired from the department after more than 35 years of service. In addition to his research, Dr. Wenger served as Vice-Chair of the department until 2013, and was course director of Medical Pharmacology until 2014. His research studied drug effects on aspects of cognitive function in laboratory animals, and more recently, included examining the relationship between substance abuse and learning and memory. This included looking at the relationship of alcohol preference and cognitive function in rats that had been selectively bred to exhibit a high alcohol to water preference or a low alcohol to water preference. Dr. Wenger remains involved with the department, serving as the alumni director.
Piotr Zimniak, Ph.D., Professor Emeritus
Dr. Piotr Zimniak (shown here with his wife, Dr. Ludwika Zimniak), retired from the Department on November 1, 2012. The Zimniaks joined the department in 2002 with Piotr as a Professor and Ludwika as a Research Associate Professor. During the past 10 years, their NIH-funded research focused on the physiological and toxicological role of lipid peroxidation in obesity and aging. Piotr also was the recipient of a VA Research Career Scientist Award. The Zimniaks retired to California to be closer to family.
