Clinical Care
Overview
Caitlin Ryus, MD, MPH, is an emergency physician at Yale Medicine with a focus on health equity, substance use disorders, and improving care for marginalized populations, particularly those experiencing homelessness. In her role, she treats a broad range of critical medical conditions, responding to patients in acute distress as well as those who experience barriers to routine care.
"I chose emergency medicine because it is a specialty that combines clinical care with public health." Dr. Ryus says. "What I find most rewarding is the ability to make an immediate impact, whether that’s providing life-saving interventions or connecting patients to services that address the root causes of their health issues."
As the co-director of the Yale Emergency Scholars Fellowship, she trains future leaders in academic emergency medicine, fostering their clinical skills alongside their research development.
