Associate Professor, Fischell Department of Bioengineering
Affiliate Faculty, Biophysics Program
​Affiliate Faculty,
Biological Sciences Program
​Affiliate Fellow, Fischell Institute for Biomedical Devices
​
​

Gregg earned his Ph.D. in Chemical Engineering under the guidance of Michael Bevan at Johns Hopkins University. His Ph.D. research focused on developing novel microparticle-based measurements and complementary models of multivalent biomolecular interactions. During his postdoctoral training, he developed nanoparticle-based diagnostic and viral gene therapy approaches for cystic fibrosis (CF) lung disease at Johns Hopkins School of Medicine in the Center for Nanomedicine directed by Justin Hanes. Gregg became a faculty member in the Fischell Department of Bioengineering at the University of Maryland, College Park in 2017. He also currently serves as the Director of the Bioengineering Honors program. He is the recipient of several honors and awards including the Burroughs Wellcome Fund Career Award at the Scientific Interface, BMES-CMBE Rising Star Award, BMES Rita Schaffer Young Investigator Award, ORAU Ralph E. Powe Jr. Faculty Enhancement Award, and the NSF CAREER award.
