Ralph Corey


My research is based at the Duke Global Health Institute, as well as the Duke Clinical Research Institute. Combining the global networks at DGHI with the clinical research expertise of our group, it has been able to design and conduct both small local studies to worldwide trials.

The focus of my research has included leishmania and malaria as well as gram positive bacterial infections: complicated skin and skin structure infections; postoperative wound infections; community-acquired, hospital-acquired and ventilator-associated pneumonia; prosthetic joint infections; bacteremia; and endocarditis (involving the International Collaboration on Endocarditis centered at Duke). The team of investigators with whom I work has tremendous collegiality and are amazingly productive.

As a result of my longstanding interest in global health and tropical medicine as well as the generosity of the Hubert, Yeargan, and Hock families, we have been able to establish the Hubert-Yeargan Center for Global Health. As part of our focus on developing innovative global health training within graduate medical education we have partnered with the Duke Global Health Institute to create the Global Health Residency/Fellowship (GHRF) Pathway, a global health program engaging trainees from multiple departments in research and service targeting disadvantaged populations. Distinctive features of the GHRF pathway include broad cross-departmental participation, rigorous didactic training through the Master of Science in Global Health program, and nine months of field experience in a resource-poor setting.
