Welcome

Jonathan Sellon I'm a postdoctoral associate in the Research Laboratory of Electronics at MIT. I recieved my Ph.D. from the Harvard-MIT Program in Health Sciences and Technology in September 2016 and S.M. in Electrical Engineering and Computer Science in February 2013, advised by Dennis Freeman in the MIT Micromechanics group. Prior to MIT, I recieved my B.S. in Biological Chemistry, B.A. in Chemistry, and B.A. in Biological Sciences from the University of Chicago. This page contains links to publications and talks I have authored.
