About

I am currently a Ph.D. candidate at Department of Computer Science and Engineering, University of Michigan, Ann Arbor. I am lucky to work in our awesome Cross-Layer Architectures and Runtimes in Ten Years Laboratory under the supervision of Professor Lingjia Tang and Professor Jason Mars. Check out my CV and Google Scholar if you are interested.
