Matt Reynolds is an Associate Professor in the Departments of Electrical Engineering and Computer Science & Engineering (joint appointment) at the University of Washington. He was previously the Nortel Networks Assistant Professor in the Department of Electrical and Computer Engineering at Duke University. He is also co-founder of the RFID systems firm ThingMagic Inc (acquired by Trimble Navigation), the energy conservation firm Zensi (acquired by Belkin), and the home sensing company SNUPI Inc (acquired by Sears).

Matt's research interests include RFID, energy efficiency at the physical layer of wireless communication, and the physics of sensing and actuation. Matt received the Ph.D. from the MIT Media Lab in 2003, where he was a Motorola Fellow, as well as S.B. and M.Eng. degrees in Electrical Engineering and Computer Science from MIT. He is a Senior Member of the IEEE, has received five Best Paper awards, and has 25 issued and over 40 pending patents.
