Dr. Julie Pfeiffer is a Professor of Microbiology at the University of Texas Southwestern Medical Center in Dallas. She received a B.A. in Microbiology from Miami University in 1996. She earned a Ph.D. in Microbiology from the University of Michigan in 2001. Her thesis work on retroviral recombination was performed in the laboratory of Dr. Alice Telesnitsky and earned the MacNeal Distinguished Thesis Award. From 2001 through 2005, she performed postdoctoral research in Dr. Karla Kirkegaard’s laboratory at Stanford University where she examined RNA virus evolution and pathogenesis and was supported by a fellowship by the Damon Runyon Cancer Research Foundation. In 2006, Dr. Pfeiffer started her independent laboratory at UT Southwestern with a focus on RNA virus pathogenesis, population dynamics, host barriers, and antiviral drug resistance. Her recent interests include examining the impact of intestinal microbiota on enteric virus infections. Her lab has determined that intestinal bacteria promote replication of several enteric viruses and ongoing work is examining mechanisms and consequences of bacteria-virus interactions. Dr. Pfeiffer was named a Pew Scholar in 2007, a Burroughs Wellcome Fund Investigator of the Pathogenesis of Infectious Disease in 2012, and a Howard Hughes Medical Institute Faculty Scholar in 2016. In addition to serving on NIH Virology B Study Section and the Annual Review of VirologyEditorial Board, Dr. Pfeiffer is an Editor at the Journal of Virology and a member of the Board of Reviewing Editors at Science.
