I am a senior software engineer at System Architecture Lab, Samsung Electronics located in San Jose, California. I am currently working on next-generation memory for accelerating machine learning and deep learning.

I received my Ph.D. at Department of Computer Science and Engineering, University of Minnesota - Twin Cities (August 2012 - May 2017). My Ph.D. advisor is Dr. David H.C. Du.

Before joining UMN, I obtained my B.E. degree in Software Engineering from Dalian University of Technology, China (August 2008 - June 2012).
