Educations and Working Experiences

I completed my Ph.D. journey at University of Bristol under the supervision of Prof. Dima Damen and I achieved my master degree in computer science at the College of Intelligence and Computing at Tianjin University from 2016 - 2019, supervised by Prof. Kun Li. Additionally, I did internships at Baidu and OPPO Research Institute, under the supervision of Dr. Yandong Guo.
