Positions

Overview

  • Dr. W. Edward Swords received a B.S. in microbiology from Auburn University, followed by a M.S. from Mississippi State University. He completed his PhD studies at the University of Alabama at Birmingham in 1996. After an ASM/NCID fellowship at the Centers for Disease Control and Prevention, Dr. Swords carried out postdoctoral work with Dr. Michael Apicella at the University of Iowa, studying the bacterial opportunist nontypeable Haemophilus influenzae. In 2002, he joined the faculty in the Department of Microbiology and Immunology at the Wake Forest School of Medicine where he established an independent research program addressing mechanisms of persistence of bacterial opportunists in otitis media and other airway infections. In 2016, Dr. Swords was recruited to join the Division of Pulmonary, Allergy & Critical Care Medicine, where he is currently a tenured Professor of Medicine. He also has appointments as a Senior Scientist in the Gregory Fleming James Center for Cystic Fibrosis Research, and a secondary appointment in the Department of Microbiology.
