Jae-sun Seo joined ASU in 2014. He received a bachelor’s degree from Seoul National University in 2001, and a master’s degree and Ph.D. from the University of Michigan in 2006 and 2010, respectively, all in electrical engineering. From January 2010 to December 2013, he was with IBM T. J. Watson Research Center, where he worked on energy-efficient integrated circuits for high-performance processors and cognitive computing chips.

During the summer of 2015, he was a visiting faculty at Intel Circuits Research Lab. His current areas of research include machine learning and neuromorphic hardware design, and on-chip voltage regulators for integrated power management. He serves on the technical program committee for ISLPED and ISOCC, and the organizing committee for ICCD.
