Ahmad R. Safa, PhD

Dr. Safa received his Bachelor of Science in Biology from the University of Esfahan, Iran, in 1973. He received his MS in General Biology in 1976, a MS in Molecular Cellular and Developmental Biology (MCDB) in 1977, and a PhD in MCDB in 1980 from Iowa State University. He joined the University of Louisville as a Postdoctoral Fellow from 1980-1983 and subsequently was a Visiting Fellow and a guest researcher at the National Cancer Institute (NCI) from 1983-1987.

In 1987, he accepted a position as an Assistant Professor of Medicine at the University of Chicago and was Director of the Laboratories of Pharmacology and Pharmacokinetics, and Molecular Pharmacology, respectively in the Section of Hematology/Oncology from 1990-1996. In 1996, he accepted a tenured Associate Professor Position in the Department of Experimental Oncology, Medical University of South Carolina (MUSC), and was promoted to tenured Professor in 1999. Dr. Safa was Director of the Drug Resistance Program at Hollings Cancer Center at MUSC from 1998-1999. In 1999, he joined the faculty of the Indiana University School of Medicine as H.H. Gregg Professor of Cancer Research, and Professor of Pharmacology and Toxicology.

Dr. Safa has been investigating the molecular and biochemical mechanisms of intrinsic and acquired resistance to chemotherapeutic drugs, apoptosis (cell death) in cancer cells, cancer stem cells, drug discovery and development, and cancer treatment. His lab is particularly interested in multi-targeted therapy of brain cancer, breast cancer, and pancreatic tumors through modulation of the death receptor signaling pathway in cancer cells.

Dr. Safa served on the Experimental Therapeutics 1 Study Section at the NCI from 1988-2002, has been an Ad hoc Grant Reviewer, Center for Scientific Review, Drug Discovery and Molecular Pharmacology Study Section since 2003, Tumor Cell Biology (TCB) Study Section, and other National Cancer Institutes (NCI) Study Sections. He has been a member of the Editorial Board of International Journal of Cell Science & Molecular Biology (IJCSMB), Journal of Cancer Research and Therapeutic Oncology. Drug Research and Development, World Journal of Pharmacology, Medicinal Chemistry, Journal of Drug Metabolism and Toxicology, International Journal of Biochemistry and Molecular Biology, Journal of Cell Death, Molecular Cancer Therapeutics, and Investigational New Drugs.
