Risha Gidwani is a senior policy researcher at the RAND Corporation. Also an associate adjunct professor at the UCLA School of Public Health, she uses both econometric and decision analysis methods to evaluate the value of health care.

Gidwani's work focuses on benefit design, cost-effectiveness, patient financial burden, and health policy. She has studied quality of care, health system costs, patient out-of-pocket costs, patient-reported outcomes, utilities, disparities, value-based purchasing, and the comparative effectiveness and cost-effectiveness of interventions. Much of her work has compared health system performance across Medicare and VA, often focusing on cancer and end-of-life care. 

Gidwani has been principal investigator on multiple peer-reviewed studies evaluating the cost and quality of U.S. health care.  Her research has been published in peer-reviewed journals such as Health Affairs, JAMA Network Open, and Medical Care, among others. 

Prior to coming to RAND, she was a health economist at the VA Health Economics Resource Center (HERC), a core investigator at the VA Center for Innovation to Implementation (Ci2i), and a consulting assistant professor at the Stanford University School of Medicine. Gidwani received her Doctor of Public Health (Dr.P.H.) degree from the UCLA Department of Health Services.
