I am a Research Assistant Professor with the National University of Singapore (NUS). Before joining NUS, I was a Senior Research Scientist with the Advanced Digital Sciences Center (ADSC), a research center of University of Illinois at Urbana-Champaign (UIUC) based in Singapore. Currently, I am working with Prof. Bingsheng He from the NUS on quite some interesting projects. I got my BS and Ph.D. degree both in Electronic Science and Technology from Nankai University in 2010 and 2016, respectively. I was also a visiting scholar of the ECE department of University of Illinois at Urbana-Champaign from 2013 to 2015.
