Zhiying “Steven” Li


Zhiying Li is a 2nd year master of science student of Electrical and Computer Engineering at University of California, Los Angeles. He finished his undergraduate in 2020 at UCLA, double majoring in Electrical Engineering and Applied Mathematics. Broadly, he is interested in robotics and smart healthcare, but he is also open to other related research area.

Currently, he is doing his graduation thesis and applying for Ph.D. program for Fall 2022.

Graudate-Level Course Projects

Wearable Triboelectric Nanogenerators (TENGs) for Closed-Loop Sensing and Therapy

Zhiying Li, Bijie Bai, Jingxi Li, Ken-Fu Liang

UCLA BE 298 Wearable Bioelectronics by Prof. Jun Chen in Fall 2020

Report   Presentation

We conducted a literature review in the frontier of the field of Wearable Triboelectric Nanogenerators. Our team gave a presentation and wrote an review writeup of this particular field.

Linear Programming Decoder for Group Testing for COVID 19

Zhiying Li, Sunay Bhat, Samuel Gessow, Terri Tsai, Dominic Yang

UCLA EE 236A Linear Programming by Prof. Christina Fragouli in Fall 2020


We designed and implement a Group Testing decoding algorithm. Group testing has a long history has recently attracted a lot of attention in the context of Covid, as a strategy that can allow to significantly reduce the number of tests used. In this project, we took into account community structure to improve the performance of the linear program decoding group testing employs.

Investigating Proximal Policy Optimization in OpenAI Gym and Roboschool Environments

Zhiying Li, Urmi Bhaumik, Hamlin Liu, Terri Tsai

UCLA EE 239AS Reinforcement Learning by Prof. Lin F. Yang in Spring 2021

Report   Posters   Video

We have demonstrated the theoretical interpreation of Proximal Policy Optimization, and conducted simulation and retrived results on LunarLander-v2 and RoboSchoolAnt-v1. Two environments are chose specifically in order to implement the algorithm on one discrete action environment and one continuous action environment.
