Ayman Fayed received his B.Sc. in Electronics & Communications Engineering from Cairo University in 1998, and his M.Sc. and Ph.D. in Electrical & Computer Engineering from The Ohio State University in 2000 and 2004
respectively. From 2000 to 2009, he held several technical positions in the area of analog and mixed-signal design at Texas Instruments Inc., where he contributed to many product lines for wire-line, wireless, and
multi-media devices. From 2000 to 2005, he was with the Connectivity Solutions Dept. at TI, where he worked on the analog frontend design of high-speed wire-line transceivers such as USB, IEEE1394b, and HDMI, and on
fully integrated switching/linear regulators and battery chargers for portable media players. From 2005 to 2009, he was a member of the technical staff with the wireless analog technology center at TI, where he worked on
delta-sigma data converters for various wireless standards, and on the development of fully-integrated power management solutions for mixed-signal SoCs with multi-RF cores in nanometer CMOS. Dr. Fayed joined the Dept. of
Electrical & Computer Engineering at Iowa State University in 2009, where he held the Northrop Grumman Assistant Professorship. He then joined the Dept. of Electrical & Computer Engineering at The Ohio State University
in 2015 as an associate professor. He is the founder and director of the Power Management Research Lab (PMRL) and his current research interests include on-chip power grids for dynamic energy distribution in
highly-integrated systems, high-frequency switching regulators with on-chip and on-package passives for SoCs, low-noise power supply modulators for RF transmitters, energy-harvesting platforms for power-restricted &
remotely-deployed systems, and power conversion in emerging technologies. Dr. Fayed is a senior member of IEEE, an associate editor for IEEE TCAS-II, and serves in the technical program committee of RFIC, ISCAS, and the
steering committee of MWSCAS. He is a recipient of 2013 NSF CAREER Award.
