Biography

Han Wang is a Full Professor and Associate Head in the Department of Electrical and Computer Engineering. He also serves as the Director of HKU Center for Advanced Semiconductors and Integrated Circuits (CASIC) and Co-Director of the Institute of Mind at HKU. He received the B.A. degree in electrical and information science from Cambridge University in 2007 and his PhD degree from Massachusetts Institute of Technology (MIT) in 2013. From 2013 to 2014, he was with the Nanoscale Science and Technology group at IBM T. J. Watson Research Center. In 2014-2023, he was with the Department of Electrical and Computer Engineering at the University of Southern California, first as an Assistant Professor and then as a tenured Associate Professor. In 2021-2023, he led the low dimensional materials research department at Taiwan Semiconductor Manufacturing Company (TSMC), in parallel to his faculty position at USC. His research interests include advanced microelectronics technology based on emerging semiconductor materials and devices for AI hardware, beyond-von-Neumann computing, communication and infrared sensing.

His work has been recognized with numerous awards including the United States Army Early Career Award for Scientists and Engineers (Army-ECASE), IEEE Nanotechnology Council Early Career Award, the United States Army Research Office Young Investigator Award, US National Science Foundation CAREER Award, USC Viterbi Junior Faculty Research Award, USC Zumberge Faculty Research Individual Award, the Roger A. Haken Best Paper Award in IEEE International Electron Device Meeting (IEDM), the Best Paper Award in International Conference on Compound Semiconductor Manufacturing Technology (CSMANTECH) and the MIT Jin-Au Kong Best Doctoral Thesis Award. He is the IEEE Nanotechnology Council Distinguished Lecturer 2020-2021. He is the recipient of the Orange County Engineering Council (OCEC) Outstanding Educator Award for contributions to science and engineering education in the Los Angeles area. He is the Clarivate Highly Cited Researcher for all the past seven years 2018-2024.
