About
Hi! I'm Zheng Li. Currently, I'm a PhD student in Computer Science and Engineering at the University of Michigan, Ann Arbor, where I am advised by Professor Jiasi Chen. My research interest lies in Multimedia System, Computer Networks, and Mobile Computing. I received a B.S.E. in Computer Science from the University of Michigan, Ann Arbor and a B.S.E. in Electrical and Computer Engineering from Shanghai Jiao Tong University through a dual degree program. When I was an undergrad at the University of Michigan, I was a research assistant in RobustNet Lab led by Professor Z. Morley Mao and MAVENS Lab led by Professor Jiasi Chen. Click here to view my CV.

Fun
Some of my other interests (outside of research!):
- Travelling: I love travelling to different places and meeting different people and culture. I've been to more than half of the provinces in China (about 20).
- Beetle: I've been breeding beetles for more than 10 years and I also have the experience of breeding reptiles.
- Running: I'm a runner and I've won several medals in Man's 1500m and 800m back in high school days.
My hometown is Wenzhou, a city located at east of China. It is known as the cradle of mathematicians.
I did Physics and Mathematical Olympiad in high school.
