About: Steve is an Assistant Professor of Epidemiology and Biostatistics at the University of Georgia and served as the ICI3D Program Director from 2016-2018. He has been involved as an organizer and instructor of the MMED and DAIDD clinics since 2009, after attending precursor workshops in 2007-2008 as a student. Steve’s background includes logistically challenging field work studying anthrax and rabies outbreaks in Namibian wildlife, as well as experience with a variety of mathematical, statistical and computational methods. His research projects span numerous pathogens and are united under the overarching theme of using mechanistic modeling and high performance computing to plan and interpret empirical studies. One of Steve’s current projects centers on understanding heterogeneity in HIV transmissibility across individuals, explaining the dramatic variation in HIV epidemic severity across Africa. A second research focus aims to optimally navigate the scientific and ethical tradeoffs involved in vaccine efficacy trials during emerging epidemics of pathogens such as the Ebola and Zika viruses.
