From 1999 till 2007, he was with the Components Research division at
Intel Corporation in
Hillsboro, Oregon. He was a Principal Engineer in the Advanced Transistor and Nanotechnology Group at Intel. He was a member of the Intel transistor R&D team that pioneered several generations of advanced logic transistor technologies such as
high-k/metal gate
CMOS, non-planar Tri-gate CMOS, and strained Si/SiGe channel CMOS. He has also led many novel transistor research programs including compound semiconductor based
MOSFET and
Tunnel FETs. More recently, his research team has investigated phase transition
solid-state devices to implement
continuous-time dynamical systems and explore their applications in solving hard optimization problems in
computer science. He was a professor of
Electrical Engineering at the
Penn State University from 2007 to 2015. for his contributions to high-performance advanced silicon and compound semiconductor transistor technologies. In 2016, he was named Fellow of the
National Academy of Inventors in recognition of his inventions that have made a tangible impact on quality of life, economic development and the welfare of society. As of December 2025, he has authored or co-authored over 850 publications in journals, conferences and granted patents and 43,000 citations. == Awards ==
