Biography
David is a fifth-year PhD candidate advised by Prof. Z. Morley Mao at the EECS department (Computer Science and Engineering division) of University of Michigan, Ann Arbor.
He received an MPhil (Master of Philosophy) and bachelor degree (first-class honour) in Computer Science and Engineering from The Hong Kong University of Science and Technology (HKUST).
His current research focuses on software performance and security problems for emerging smart systems including connected and autonomous vehicles, smartphones, etc.
He also did network and system research in software-defined networking and cloud data centers.
Prior to the college study in Hong Kong, David was born and brought up in Chaozhou, a cozy and serene coastal city in the east of Guangdong, China.
He spent most of his teenager life studying at Chaozhou Jinshan Middle School.
