This Ph.D. has over 28 years of experience in the semiconductor industry,with a specific emphasis on the physics of semiconductor devices.  He held technical positions at Stanford University, Purdue University, and the German Space Agency in Stuttgart-Vaihingen, Germany.  For over 25 years he has worked in the semiconductor industry, first at Siemens and then at Motorola, whose semiconductor division later became Freescale Semiconductor.  Since 2008 he has been a Professor at Virginia Tech, where he continues his research in semiconductor device physics and technology.

His research in semiconductor device physics at Motorola had a specific emphasis on non-volatile memories and associated physical effects, such as band-to-band tunneling.  In 1990, he was the first to simulate band-to-band tunneling in MOSFETs, and correctly predicted new modes of tunneling.  In addition, he researched the impact of band-to-band tunneling on non-volatile memories.  In addition to conducting research in semiconductor physics, he successfully managed the development of several technologies, like a 50nm fully depleted silicon-insulator (SOI) MOSFET with TiN/HfO2 gate stack,and a 30nm gate length SOI MOSFET.

This Ph.D. is the lead inventor on most of the 109 patents issued, and has over 240 publications in scientific journals and conference proceedings.
