Since 2003, I have been working with GHESKIO in Haiti, where my research activities have focused on collaborations to evaluate the cost-effectiveness of rapid syphilis screening in prenatal HIV testing programs and the cost of providing antiretroviral therapy for HIV. I also work with GHESKIO investigators who are conducting clinical trials of HIV treatments and vaccines. I teach and mentor Haitian students in a two-week MPH course on health services research and cost-effectiveness analysis. The MPH program is run as a collaboration between Quisqueya University in Port-au-Prince, GHESKIO, and WCMC. I spend approximately 1-2 weeks in Haiti each year. My Cornell faculty collaborators include Dan Fitzgerald, Warren Johnson, and Jean Pape. Students interested in getting involved in health services research in Haiti should contact Dan Fitzgerald.
