About

Hi! I’m Zheng Li. Currently I’m a senior student majoring in Computer Science at University of Michigan, Ann Arbor. My research interest lies in Computer Network, Machine Learning and Human Computer Interaction. At University of Michigan, I’m fortunate to work as a research assistant in RobustNet Lab led by Professor Z. Morley Mao and SODA Lab led by Professor Jiasi Chen. I’m also pursuing a dual degree of Electrical and Computer Engineering at Shanghai Jiao Tong University, where I worked closely with Professor Pradeep Ray in the Center for Entrepreneurship.

Research

1. Starlink Project @ RobustNet Lab, January 2023 - Present

   Supervisor: Professor Z. Morley Mao

   Reviewed current literatures about network system design of Low Earth Orbit satellites (LEO) and their advantages/disadvantages.

   Developed a customized network performance measurement system that can measure basic network performance parameters including round trip time, throughput etc. for Starlink.

   Implemented handover recognition algorithms for LEO handover problems based on round trip time and throughput measurements.

   Implemented Satellite trajectory prediction using Kalman filter.

2. Robotics for Autism @ JI Centre for Entrepreneurship, July 2021 - August 2022

   Supervisor: Professor Pradeep Ray

   Constructed a low-cost autism diagnosis system using eye-tracking technologies based on computer vision.

   Reviewed current robotic technologies used in Autism diagnosis and treatment and published a paper on AHHM based on the review.

Selected Project

1. Emotion Classifier for Reddit Post

   Trained machine learning model to classify the emotions in Reddit posts.

   Did feature engineering and used several different machine learning classifiers including LinearSVM, QuadraticSVM etc. to improve classification correctness. Finally improved the accuracy by 10% compared with the original basic LinearSVM model.

2. Dog Classifier

   Trained machine learning model to classify different dog breeds.

   Used Gradient-weighted Class Activation Mapping to visualize features used by CNN.

   Applied transfer learning and data augmentation to improve classification correctness. Finally improved the accuracy by 12% compared with the original CNN model.

3. MiProxy

   Built a Proxy that can handle video streaming requirements between multiple clients and servers.

   Implemented adaptive bitrate selections for video streaming to minimize annoying buffering and improve user experience.

   Realized distance based server selection using Dijkstra algorithm.

4. Static Router

   Implemented a static router with basic router function like packet forwarding.

   Implemented layer 2 and layer 3 protocols including ARP, ICMP, Ethernet etc.

5. SillyQL: A Simplified Query Language

   Implemented a program that support basic SQL commands including insert, select, join, where etc.

   Used hash map and binary searching tree to accelerate some commands’ execution.

6. Insta485: A Simulation Program for Instagram

   Implemented a static site generator that can automatically produce HTML templates for static web pages.

   Implemented an Instagram clone that has basic Instagram functions with server-side and client-side dynamic pages.

7. Map - Reduce Searching Engin

   Created a segmented inverted index of web pages using a pipeline of MapReduce programs.

   Built an Index server, a REST API app that returns search results in JSON format.

   Built a scalable Search server with a user interface that returns search results like Google or Bing.

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 severl 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.
