Megan Freeman, MD, PhD
- Assistant Professor
- Pediatrics
Megan Culler Freeman, MD, PhD is currently a senior Pediatric Infectious Diseases fellow at UPMC Children’s Hospital of Pittsburgh. She completed her Bachelor of Science degree at the University of Kentucky, and then earned her M.D. and Ph.D. degrees at Vanderbilt University, where she studied coronaviruses. Freeman has authored multiple publications in the field and the coronavirus book chapter in the most recent edition of Nelson Pediatrics. She completed her Pediatrics Residency at Children’s as part of the Pediatric Scientist Development Program (PedSDP). She currently works in the laboratory of John Williams, MD, where her research interests include pathogenesis and cell biology of RNA viruses and advanced tissue modeling, with a current focus on enterovirus D68, the hypothesized cause of acute flaccid myelitis (AFM) in children. Freeman is the proud recipient of the Pediatric Infectious Diseases Society-St. Jude Children’s Research Hospital Fellowship Program in Basic and Translational Research.
