Matthew Fainor

Research Engineer
University of Pennsylvania

Hometown

Allentown, Pennsylvania

Education

B.S. IDEAS (Integrated Degree in Engineering, Arts & Sciences) concentrating in Biomaterials & Biomechanics Engineering and Art & Design, Lehigh University, 2020

Areas of Special Interest

Matthew's interests include tissue engineering, composite biomaterials, and living materials of all kinds. Outside of the lab, Matthew can be found hiking, collaging, making art, knitting, going to concerts, or just sitting on his couch binging reality competition TV. Matthew also writes--shorts for himself and science reporting for his blog Fleshy Futures.
