Bio

Andrew M. Dahlem, D.V.M. (h.c.), Ph.D., serves in a part time capacity as Senior Research Professor of Medicine and Chief, Division of Clinical Pharmacology, at the Indiana University School of Medicine, in Indianapolis, Indiana, since November of 2018. Dr. Dahlem is also Chief Development Officer at Gate Neurosciences, a novel biotechnology company focused on new therapies for treatment resistant depression and President of Dr. Dahlem Consulting. Dahlem retired from Eli Lilly and Company in December of 2017 after nearly 28 years of service. At the time of his retirement, Dr. Dahlem had been vice president and chief operating officer for Lilly Research Laboratories (LRL) and LRL Europe for more than 10 years and reported to the President of Lilly Research Laboratories. He previously served as vice president of toxicology, drug disposition, pharmacokinetics, and Lilly Research Laboratories in Europe since January 2003 and was a member of Lilly senior management. Dr. Dahlem received a bachelor of science degree from The Ohio State University in 1982 and a doctor of philosophy degree in toxicology from the College of Veterinary Medicine at the University of Illinois at Urbana-Champaign in 1989. In 2014 he was awarded a Doctor of Veterinary Medicine Degree (honoris causa) from the College of Veterinary Medicine at Purdue University. Dahlem began his career in pharmaceutical research in the metabolism group of Merrell Dow Pharmaceuticals and then joined Lilly in 1990 as a senior pharmacologist where he worked on improving the ADME properties of molecules to treat Alzheimer’s Disease and HIV/AIDS. His laboratory led the improvement of molecular absorption properties for HIV protease inhibitors and designed and conducted ADME studies in support of the registration of Nelfinavir (Viracept). He became head of biochemical toxicology in 1992. He was named director of drug disposition and biochemical (investigative) toxicology in 1993. He was promoted to executive director for toxicology and drug disposition in 1998, and he assumed responsibility for LRL in Europe in 1999 and for discovery operations in 2000. In December 2001, he was promoted to Vice President. While at Lilly, Dr. Dahlem had shared accountability for research and development portfolio entry and exit decisions from Candidate Identification through Phase 2. He led groups responsible for clinical trial design and execution optimization across the portfolio, competitive intelligence, due diligence, academic outreach, as well as the core operational support function of Lilly Research Laboratories. He is a strong advocate of decision science methodology to drive portfolio outcomes. Dr. Dahlem has served as adjunct professor of toxicology in the Colleges of Veterinary Medicine at Purdue University, the University of Illinois at Urbana-Champaign, and at The Ohio State University. He is a member of The Ohio State University College of Pharmacy Corporate Council and The Ohio State University’s Center for Clinical and Translational Science External Advisory Board. He is also a member of the Indiana University Clinical and Translational Sciences Advisory Council and the Strategic Research Advisory Council at Purdue University. Dr. Dahlem currently serves on the board of directors for Indigo Biosystems and was the Lilly leader who proposed its formation. He has been appointed by the Governor of Indiana to the Indiana State Museum Foundation Board of Directors. He is a past member of the Institute of Medicine Forum on Drug Discovery, Development and Translation and the Translational Research and the Critical Path for Tuberculosis Drug Regimens for the Gates Foundation. Dr. Dahlem also is a member the International Union of Pure and Applied Chemistry and represents Indiana University’s interests in the society. In addition to his scientific interests, Dr. Dahlem is passionate about driving gender parity in the workforce and was the executive sponsor for the Women in Lilly Discovery and Development support group in Lilly Research Laboratories for more than a decade.
