Biography

I received the B.S. degree in electronics and information engineering in 2012 and the Ph.D. degree in communication and information system in 2017 from Sichuan University, Chengdu, China, where I was supervised by Prof. Xiaohai He (Sichuan University). From 2015.9 to 2016.10, I was a visiting scholar with the Department of Electrical and Computer Engineering, University of California at San Diego, CA, USA, under the supervision of Prof. Truong Nguyen. I am currently an assosiate research professor with the College of Electronics and Information Engineering, Sichuan University, and has received the support from National Postdoctoral Program for Innovative Talents of China, and National Natural Science Foundation of China.

I got the highest average score (about Top 0.5%, 1/200) in the department of information and communication engineering at Sichuan University during my undergraduate study, and has received various contest awards (e.g., National Undergraduate Electronic Design Contest, 2011) and scholarships (e.g., National Scholarship, 2016).
