Biography
I am a tenure-track assistant professor in the Department of Computer Science at the University of Oregon. I was a Computer Scientist in Computer Science and Mathematics Division at Oak Ridge National Laboratory mentored by Dr. Dave Pugmire and Dr. Scott Klasky. I received a Ph.D. degree in Computer Science from University of California, Riverside advised by Dr. Zizhong Chen in 2019. I had a research internship at Pacific Northwest National Laboratory (PNNL) mentored by Dr. Shuaiwen Song in 2018 and a long-term research internship at Los Alamos National Laboratory (LANL) in the Data Science at Scale (DSS) team mentored by Dr. Qiang Guan and Dr. James Ahrens in 2017. I received a Master degree in Computer Science at University of California, Riverside in 2014. I had an one-year undergraduate visit study at The State University of New York at Buffalo in 2011-2012. I received a Bachelor degree in Computer Science from Beijing University of Technology in 2012.
I'm looking for outstanding Ph.D. students who are interested in HPC, LLM, GPU computing, and distributed systems. Please send your CV and transcript via email. [learn more]
