Tobias Gerhard (PhD, Pharmacoepidemiology, University of Florida, 2007; BS, Pharmacy, Albert-Ludwigs University, Germany, 2002) is an associate professor of Pharmacoepidemiology at the Rutgers Ernest Mario School of Pharmacy. He also serves as Associate Director of the Center for Health Services Research on Pharmacotherapy, Chronic Disease Management, and Outcomes at the Rutgers Institute for Health, where he conducts research on use, safety, and outcomes of prescription drugs, particularly those used to treat mental health conditions. He is interested in epidemiological methods and their applications in the analysis of large administrative databases and has published and presented on a wide range of topics including attention deficit hyperactivity disorder, autism spectrum disorders, cardiovascular disease, epidemiological methods, pharmacogenetics, and pharmacoeconomics.
His current research includes the comparative safety and effectiveness of antipsychotic medications, pharmacological treatments for dementia, and more generally research on the use and management of psychotropic medications in Medicaid, Medicare, and privately insured populations. He is a Fellow and Board Member of the International Society for Pharmacoepidemiology (ISPE) and currently serves on FDA’s Drug Safety and Risk Management Advisory Committee. Dr. Gerhard is the recipient of a NARSAD Young Investigator Award, a NCDEU New Investigator award and currently serves as Co-Principal Investigator of the AHRQ-funded Rutgers Center for Education and Research on Mental Health Therapeutics (CERTs).
