  6. Author Bio

Gregory L. Charvat is author of Small and Short-Range Radar Systems, Co-Founder of Butterfly Network Inc., and advisor to the Camera Culture Group at MIT Media Lab.  Greg grew up in the metro Detroit area, where, at a young age he would take apart old television sets and radios.  Greg eventually started making amateur radio equipment in high school, a radio telescope, and developed numerous radar systems while in college.  He earned a PhD in electrical engineering in 2007, MSEE in 2003, and BSEE in 2002 from Michigan State University.  He was a technical staff member at MIT Lincoln Laboratory from September 2007 to November 2011 and has taught short radar courses at the Massachusetts Institute of Technology where his work on Through Wall Radar Imaging is a MIT Office of the Provost 2011 research highlight and his ‘Build a Small Radar Sensor...’ course was the top-ranked MIT Professional Ed. course in 2011. 

Dr. Charvat authored or co-authored numerous journals, proceedings, magazine articles, and seminars on various topics including; applied electromagnetics, synthetic aperture radar (SAR), and phased array radar systems, RF and analog design.  He has developed numerous rail SAR imaging sensors, phased array radar systems, impulse radar systems, holds several patents, has developed many other radar sensors, and designed his own amateur radio station.  For fun Greg develops vacuum tube audio equipment, restores antique radios, watches, clocks, likes to go Lindy-hop dancing, and sails on the Long Island Sound.  He won best 2010 paper at the MSS Tri-Services Radar Symposium for his work on through wall radar.  Press on this work can be found on the front page of mit.edu news, in Slashdot, Popular Science blog, MIT CSAIL news, ABC news, CNN blog, Financial Times, Popular Mechanics Blog, PC Magazine, Fox News Boston, BBC News, Wired UK, Discovery News, R & D Magazine, MSNBC online, MIT Alumni News, The State News, Wall Street Journal, Make Magazine blog, IEEE Spectrum Magazine , QST Magazine, and others.

Greg is a Senior Member of the IEEE.  He served on both the 2010 and 2013 IEEE Symposium on Phased Array Systems and Technology steering committees, on the steering committee for the CMU 2012 Next Generation Medical Imaging Workshop, served as chair of the IEEE AP-S Boston Chapter from 2010-2011, and IEEE Boston Section Member at Large in 2012.
