Hello!

I am an Assistant Professor at University of Central Florida (UCF), Department of Computer Science. I generally develop architecture/compiler co-design solutions to improve performance, reduce hardware complexity, and address reliability/security problems. I received my Ph.D degree from Purdue University under the guidance of Prof. Changhee Jung in 2022. Prior to joining in UCF, I worked at ARM Research in 2020 Summer with Prof. Fredrik Kjolstad in Stanford and COMMIT group in MIT. I also worked for NASA EpSCoR under Prof. Alexandre Martin at University of Kentucky (2017). I was a research engineer at LG Electronics Car Laboratory studying about high performance embedded system design (2012-2015). I was honored to receive an ACM SIGBED Paul Caspi Memorial Dissertation Award (2023).

I am actively looking for highly-motivated postdoc/Ph.D students who are excited about computer architecture, compiler, and system research. Please email me your CV, if you are interested in the research.
