Putnam lab is excited to welcome a new post doc, Zhexun (Jason) Sun! Jason completed his PhD in 2018 at Cornell University in Ithaca, New York, where he worked with Prof. David Putnam in Biomedical Engineering. In his short time among us, we are confident that Jason will make an excellent addition to the Putnam lab, based on his extensive knowledge of biomaterial synthesis and outstanding performance as a laboratory safety officer. In his free time, Jason enjoys skiing, rock climbing, and wine tasting. Welcome, Jason!
