Mark K. Meiselbach, PhD, is a health economist and Assistant Professor in the Department of Health Policy and Management at the Johns Hopkins University Bloomberg School of Public Health. His research focuses, first, on the policy and market conditions that influence what insurers offer in privately managed insurance markets, including employer-sponsored insurance, Medicare Advantage, and Medicaid-managed care. Further, his research seeks to understand the potential downstream consequences of those decisions on enrollees, with a particular focus on access to treatments for mental health and substance use disorders. His work has been published in leading economics, health policy, and medical journals, including the Journal of Health Economics, American Journal of Health Economics, Health Affairs, and JAMA-Internal Medicine.

He received his PhD in Health Economics and Policy from the Johns Hopkins Bloomberg School of Public Health and his Bachelor’s degree in Quantitative Economics and Biology from Tufts University and his PhD from Johns Hopkins.
