Alexa N. Roth, PhD
- Postdoctoral Fellow
Administrative Assistant: Colleen Kelly
Dr. Alexa Roth joined the laboratory of Dr. Terence Dermody at the University of Pittsburgh in early 2020. As a postdoctoral fellow, she contributes to hands-on work in the lab and collaborates with her labmates to advance research in virology. Alexa discovered her passion for viral pathogen-host interactions while engaged in undergraduate studies at the University of Florida (UF). Upon receiving her BSc in microbiology and cell science, she remained at UF to pursue doctoral studies in the Graduate Program in Biomedical Sciences, where she studied links between cells infected by norovirus and development of diarrheal disease under the mentorship of Dr. Stephanie Karst. Alexa received her PhD from the University of Florida in 2019. Here in the Department of Pediatrics, Alexa is currently researching aspects of reovirus pathogenesis in the gastrointestinal tract. She plans to develop a research program studying enteric virus biology as she pursues a career as an independent scientist in academia.
