I am an Associate Professor of the Computer Science Department and I won the 2015 Texas State University Presidential Award for Excellence in Scholarly/Creative Activities. I received my Ph.D. degree in Computer Science and Software Engineering from Auburn University in 2008 with the Distinguished Dissertation Award. I received my B.S.(2002) and M.S.(2005) degrees in Computer Science from Shandong University, China.

My research is currently focusing on Energy-Efficient Computing and Systems, Big Data Analytics, Parallel Programming, and Mobile Computing. I serve as the associate editor of Sustainable Computing Journal (SUSCOM). We welcome qualified and self-motivated students to join us in projects related to these areas.


Congratulations for Stuart, Sarah, Sang, Divya, Donna, Zach, Joal, and Xinbo received job offers from Google, Intel, LinkedIn, Dell, GM, Raytheon, Spiceworks and Plantronics!






At SC15, we released Greencode, the cloud-based IDE that compiles and runs codes written in more than 20 languages and reports the performance and energy consumption of the codes. Try it out!
