Monika Safford, M.D., Director of Research

Under the leadership of Monika Safford, M.D., our Division's research program is driven by a mission to reduce health disparities and improve outcomes for individuals living with chronic conditions. Our work spans clinical epidemiology, health services research and community-based interventions, with a strong emphasis on vulnerable populations both in the U.S. and globally.

GIM research faculty seek to reduce care fragmentation, improve patient-physician communication, and close healthcare gaps. Our research also targets evidence-based clinical interventions, climate-related health threats, and community-based research to drive policy change and allocate more resources to high-need population.

We aim to impact healthcare policy by enhancing home care for older patients, developing clinical strategies, and addressing social determinants of health. We focus on health equity and behavioral health, especially for those affected by food insecurity and poor social conditions. Our research also combats misinformation, improves doctor-patient communication, and emphasizes culturally relevant health interventions in Latino communities. These research areas reflect a strong commitment to reducing racial and ethnic disparities, improving patient education, and enhancing healthcare delivery for chronic conditions.
