Hello!

I am a Ph.D candidate at Purdue University, Department of Computer Science, being advised by Dr.Changhee Jung. I generally develop architecture/compiler co-design solutions to improve performance, reduce hardware complexity, and address reliability/security problems. I am currently building energy harvesting systems. Before joining CS@Purdue, I received BS/MS from Kentucky State University advised by Prof. Chi Shen and Prof. Jens Hannemann. From 2012 to 2015, I was a research engineer at LG Electronics Car Laboratory studying about high performance embedded system design.


News

I will join as an (tenure-track) assistant professor in the Department of Computer Science and Cyber Security and Privacy Cluster (CyberSP) at University of Central Florida in Fall 2022.
