She loves to hike, watch baseball, read books, and play piano.

Michael Schwoerer, PhD

  • Michael is a postdoctoral fellow in the lab interested in host-viral interactions in the lung epithelium. He seeks to understand how specific viral processes drive functional tissue-level changes, with broad implications for asthma, post-acute inflammatory sequelae, and lung regeneration. Born and raised in Philadelphia, Michael received a B.A. in Biology at the University of Pennsylvania, where he carried out research on how Ebola and Lassa viruses escape the host cell. He subsequently attended Princeton University, where he earned a Ph.D. in Molecular Biology in the lab of Alexander Ploss. Michael’s graduate work focused on the extremely narrow host tropism of HCV, characterizing the species-specific effects of the interferon-stimulated gene receptor transporter protein 4 (RTP4). He is compelled by the intricacies of host-viral interactions and the ways that they can be leveraged to develop broad-spectrum therapeutics. Outside of lab, Michael enjoys distance running, opera, pub trivia, and karaoke.

Aaqib Sohail, PhD
