Assistant Professor of Molecular Microbiology and Immunology


Katherine (Katie) Siddle is an assistant professor in the Molecular Microbiology and Immunology department at Brown University. Katie is interested in how pathogens (in particular viruses) emerge, spread and evolve, and the selective pressures this places on infected hosts. To address these questions, Katie's research integrates the analysis of large biological data sets, experimentation and fieldwork to investigate the genetic diversity of emerging viruses and the role of host and pathogen genetic variation in disease severity. 

Katie joined Brown University in January 2023. Prior to this, Katie was a postdoctoral fellow at the Broad Institute of MIT and Harvard in the lab of Pardis Sabeti. Katie obtained her BA and MPhil in Biological Anthropology at the University of Cambridge, UK, and her Ph.D. in human immunogenomics from the Institut Pasteur and the Université Pierre et Marie Curie in Paris, France.
