Derek A. Cummings, PhD
Derek A. Cummings, PhD, is Assistant Professor in the Department of Epidemiology, Johns Hopkins Bloomberg School of Public Health. Dr. Cummings' interests are in bridging theoretical work on infectious disease dynamics, field work on infectious diseases and public health responses to infectious disease outbreaks. Dr. Cummings' work on the VMI includes coordinating data collecton activities and research on dengue vaccination strategies. Dr. Cummings' training is in systems research and he has worked on theoretical simulations of dengue, measles, smallpox and influenza transmission. His field work includes a community-based study of influenza in southern China, a study of dengue among non-human primates in Senegal, and a study of dengue in Thailand.
Justin T. Lessler, PhD
Justin T. Lessler, PhD, is an Assistant Professor at Johns Hopkins Bloomberg School of Public Health. The major focus of his research is the development and application of statistics, dynamic models and novel study designs to better understand and control infectious disease. In particular, Justin is interested in creating synergies between infection control practice, data collection and infectious disease dynamics. Exemplary of this goal, he and collaborators have developed methods to estimate the distribution of incubation periods for an infectious disease using coarse data, applied these methods to develop the best available estimates for a number of viruses, and showed how these estimates can be used to improve infection control practice. His current research projects include work on the transmission dynamics of influenza in southern China, and the mode effective use of vaccine in the control of measles and cholera. Dr. Lessler is the recipient of a Johns Hopkins Center for Global Health Faculty Pilot Grant and recipient of a NIAID Research Scholar Development Award (K22).
