David Rasmussen is currently a postdoctoral fellow at ETH Zurich working with Dr. Tanja Stadler on developing new phylogenetic methods for infectious disease epidemiology. He received his PhD in 2014 from Duke University, where he became interested in combing epidemiological modeling with phylogenetic methods, a field that has become known as phylodynamics. As a postdoc, he has continued to work on developing and applying phylodynamic approaches to human pathogens such as dengue, Ebola and influenza. He is currently most interested in using phylogenetics to study the epidemic dynamics of HIV and the transmission networks through which the virus spreads.
