Naoru Koizumi is a professor of public policy and associate dean of research and grants in the Schar School of Policy and Government at George Mason University. She specializes in medical policies, particularly in the fields of organ transplantation and the end-stage kidney and liver diseases.

Her research focuses on the applications of various quantitative methods such as biostatistics, Geographic Information Systems (GIS), simulation and mathematical optimization to analyze various clinical and policy questions related to organ transplantation and other chronic disease treatments. Her projects funded by the National Institutes of Health (NIH) and the National Science Foundation (NSF) include simulations and optimizations of organ allocation (NIH-R21) and bed allocation in a mental health system (NIH-R21 & R01), simulation of slum expansion in India (NSF), mathematical/simulation analyses of living donor – recipient matching with desensitization (NSF), and network analysis of illicit kidney trade networks (NSF). Her grant from the Bill and Melinda Gates Foundation investigated effectiveness of ICT-based interventions designed to enhance medication adherence among tuberculosis patients in India.

Before joining the Schar School, Koizumi was a postdoctoral researcher at the Electrical and Systems Engineering Department of the University of Pennsylvania where she worked on various health sector projects in collaboration with the School of Medicine. Outside academia, she worked for several international development agencies (IDB and EBRD) and in private consulting, participating primarily in social and environmental sector projects in Latin America and East Europe.

Koizumi completed her first doctoral program in regional science from the University of Pennsylvania in 2002. The extension of her doctoral research was funded by NIH. Her second PhD (2005) is in environmental and preventive medicine from Hyogo College of Medicine, Japan.
