Morris Cohen received his B.S. and Ph.D. degrees in Electrical Engineering from Stanford University in 2003 and 2010, respectively, and served as a research scientist there until August 2013. From September 2012 until August 2013, Dr. Cohen was appointed as AAAS Science and Technology Policy Fellow at the National Science Foundation.

In Fall 2013, he joined the faculty in the School of ECE at Georgia Tech, with promotion and tenure as of Summer 2018. He was selected for the NSF CAREER award in 2017 and received the ONR Young Investigator Award in 2015. He is the winner of the 2014 Santimay Basu Prize by the International Union of Radio Science, an award given once per three years to an early career scientist. He is an author of more than 90 journal publications and 200 conference presentations. He serves as an Associate Editor for Radio Science and as President-Elect of the Atmospheric and Space Electricity Section of the American Geophysical Union. He utilizes a "flipped classroom" model for teaching, which increases student engagement and peer interaction, and won Georgia Tech's CTL/BP Junior Faculty Teaching Excellence Award in 2018. He enjoys hiking, cooking, traveling, and building pizza ovens.
