Professor Ko’s research focuses on the health problems which have emerged as a consequence of rapid urbanization and social inequity. Dr. Ko coordinates a research and training program on urban slum health in Brazil, where his group is conducting long-term prospective studies on urban health problems which include dengue, meningitis and respiratory infections, as well as non-communicable diseases such as hypertension and violence. His work is particularly interested in understanding the natural history of leptospirosis, which is as a model for an infectious disease which has emerged in slum settlements due to the interaction of climate, urban ecology and social marginalization. On-going research combines multidisciplinary epidemiology, ecology and translational research-based approaches to identify prevention and control strategies which can be implemented in slum communities. His laboratory research group is also working to characterize virulence mechanisms in Leptospira and identify vaccine candidates for leptospirosis. Dr. Ko is the Principal Investigator at Yale for the Fogarty Global Health Equity Scholars Program which provides research training opportunities for US and LMIC post and pre-doctoral fellows at collaborating international sites.
