Dr. Ay received his MS and PhD Degrees in Electrical Engineering-Electrophysics from the University of Southern California (USC), Los Angeles, CA, in 1997 and 2004. He joined the ECE department of University of Idaho in 2007 as Assistant Professor, and promoted to tenured Associate Professor in 2013. He joined the Electrical and Computer Engineering department of WPI on early 2024.
He founded VLSI Sensors Research Group (VSRG) and Focussed Ion Bean / Scanning Electron Microscopy Laboratory (FIBSEM), in 2007 and 2016, respectively. His core focus and competence is in the wider area of Very Large Scale Integration (VLSI) circuits and system design, specifically in the area of analog/mixed-signal integrated circuit (IC) design for array sensors such as Complementary Metal Oxide Semiconductor (CMOS) type image sensors and camera systems. He worked in semiconductor industry as VLSI Design Engineer for about 10 years before joining to academia.
