About

I am an Associate Professor in the department of Electrical Engineering and Computer Science at the University of Kansas. I earned my Ph.D. in Computer Science from the University of Illinois at Urbana-Champaign in 2013. Prior to the PhD, I worked for Samsung Electronics and ETRI. I enjoy reading and running.

Research

My research goal is to build safe and secure real-time computing system infrastructure (OS, architecture, and middleware) for intelligent cyber-physical systems.

Please check the overview of my recent research. Also, check the Projects tab for more details of my current/past research projects.

According to CSRankings, which uses a publication quality based metric, KU is ranked 15th in the US in the embedded & real-time systems area due to my publications.

I am looking for motivated students who are interested in embedded systems research. Experiences in AI, OS, architecture, and robotics are a plus. Currently available positions include (but not limited to):

PhD/MS in real-time edge AI (see this )
PhD/MS in microarchitectural attcks and defenses (see this and this )
PhD/MS in time predictable high-performance heterogeneous computing platforms. (see this )
Undergraduate research assistant (URA) in autonomous car, UAV testbeds (see this)

Feel free to email me if you are interested in any of the related areas.
