    Dr. Kenneth O.

    Professor at the University of Texas at Dallas

    Professor Kenneth O. received his S.B, S.M, and Ph.D. degrees in Electrical Engineering and Computer Sci­ence from the Massachusetts Institute of Technology, Cambridge, MA in 1984, 1984, and 1989, respectively. 1

    From 1989 to 1994, Dr. O worked at Analog Devices Inc. developing sub-micron CMOS processes for mixed signal applications, and high speed bipolar and BiCMOS processes. He was a professor at the University of Florida, Gainesville from 1994 to 2009.

    He is currently the Director of Texas Analog Center of Excellence and Texas Instruments Distinguished University Chair Professor of Analog Circuits and Systems at the University of Texas at Dallas. His research group is developing circuits and components required to implement analog and digital systems operating at frequencies up to 40THz using silicon IC technologies.

    Dr. O was the President of the IEEE Solid-State Circuits Society in 2020 and 2021. He has authored and co-authored 290 journal and conference publications, as well as holding 15 patents. Dr. O has received the 2014 Semiconductor Research Association University Researcher Award. Prof. O is also an IEEE Fellow.

    Dr. Wooyeol Choi

    Assistant professor in the Department of Electrical and Computer Engineering at Seoul National University.

    Wooyeol Choi (Senior Member, IEEE) received a B.S. degree in electronic engineering from Yonsei University, Seoul, South Korea, in 2001, and the M.S. and Ph.D. degrees in electrical engineering from Seoul National University, Seoul, South Korea, in 2003 and 2011, respectively.

    From 2011 to 2018, he was with the Texas Analog Center of Excellence, The University of Texas at Dallas, Richardson, TX, USA, first as a Research Associate and later as an Assistant Research Professor. From 2018 to 2023, he was an Assistant Professor with the School of Electrical and Computer Engineering, Oklahoma State University, Stillwater, OK, USA.

    Since 2023, he has been an Assistant Professor with the Department of Electrical and Computer Engineering at Seoul National University. His research interests include designing and characterizing integrated circuits and systems for RF to terahertz frequency applications.
