Jenny S. Guadamuz, PhD's Bio

Jenny S. Guadamuz is a postdoctoral research fellow at the USC School of Pharmacy (Program on Medicines and Public Health) and the USC Leonard D. Schaeffer Center for Health Policy and Economics. She completed her PhD in pharmacoepidemiology and pharmaceutical policy at the University of Illinois at Chicago (UIC). She also holds an MS in health policy and administration from UIC and a BA in economics from Saint Louis University.

Dr. Guadamuz uses an interdisciplinary approach to identify how structural determinants (i.e., macro-level systems, institutions, and policies) impact the use of healthcare, especially medications among vulnerable populations. Her current research focuses on disparities in access to healthcare and health outcomes across immigration status. Immigration status is a critical yet overlooked factor influencing disparities because noncitizens experience significant barriers to legal and social protection, including inadequate healthcare access. She has also conducted research in the fields of drug utilization in vulnerable populations (e.g., children and older adults), policies to mitigate prescription drug risks, and the role of pharmacy accessibility in determining access to medications using cross-sectional and cohort studies, administrative claims, and geospatial data.

Dr. Guadamuz’s unique research perspective has garnered funding from the Robert Wood Johnson Foundation, as part of their inaugural cohort of Health Policy Research Scholars, and the National Heart, Lung, and Blood Institute, as a T32 fellow. Her research has been published in high-impact, peer-reviewed journals, including JAMA, the American Journal of Public Health, and Health Affairs.
