I am pursuing my PhD in Computer Science. I received my dual bachelors in Computer Science Engineering and Electronics Engineering & Computer Science from University of Michigan, Ann Arbor, USA and Shanghai Jiaotong University, China respectively in 2011. Here is my complete Resume.

Research

I work in the broad area of computer architecture with my advisor Prof. Onur Mutlu

My specific research interests are in managing heterogeneous architectures and providing hardware support for high performance scientific computing.

I am also working with Prof. Can Alkan on accelerating DNA sequence mapping.

Teaching

I enjoyed being a teaching assistant for Parallel Computer Architecture and Programming, 15-418, in Spring 2013.

I also TAed Computer Architecture, 15-740, in Fall 2013.

I had a lot of fun TAing both courses.

Internship

I interned at IBM Watson Research Center in Summer 2014. I worked on accelerating analytics applications (which typically employs machine learning algorithms) using GPUs. I worked with Jayaram K. R., Shu Tao and Anshul Gandhi. I had a great summer there.

  • Outside of Work

    I am also a quasi-actor. I have learned acting and drama for three years in high school. I am also a big fan of basketball. Used to be supporting Boston Celtics. In my spare time, I love reading philosophy and watching thoughtful movies.
