At present, I'm a third year Ph.D. student in the Department of Electrical and Computer Engineering of Carnegie Mellon University. I am fortunate to be advised by Prof.Yuejie Chi. I received my bachelor's degree from Electronic Engineering, Tsinghua University in July 2018. Here is my short CV.

My research interests include signal processing, nonconvex optimization, high-dimensional statistical estimation and reinforcement learning, ranging from theory to applications.

[2020/05/18-08/21] Internship in Mitsubishi Electric Research Laboratories (MERL) from May to August.

[2020/01/24] One paper accepted to International Conference on Acoustics, Speech, and Signal Processing (ICASSP) 2020, Barcelona.

[2019/10/15] Received Women in Machine Learning Workshop Travel Grant (2019).

Non-Wearable Three-Dimensional Display and Interaction Cube Based on Multi-Screen

Nov 1, 2016. Advisor: Huimin Ma, Tsinghua University, Beijing, China.

We designed a real-time virtual reality cubic interaction metaphor, arranged 5 LED panels into a cube to create a 3D object illusion, utilizing binocular vision to track user’s eyes and rendering the perspective of each screen to fit the user’s eyes positions.

Collaborative Distributed System based on cars/Unmanned Aerial Vehicle Coordinated Formation Design

Jul 18, 2016. Advisor: Yuan Shen, Tsinghua University, Beijing, China

We developed a multiple robot collaborative localization and navigation system using a self-made mobile robot platform. The robots in our system are equipped with a wireless distributed localization system based on UWB(Ultra Wide Band), which enables them automatically to form a pre-defined formation with mutual localization information.

Air Hockey Robot

Jun 13, 2015, Tsinghua University, Beijing, China

We built a robot to play air-hockey game with human, which is a popular table game. This robot consists of a bird-view camera (capturing the images of moving ball) and an executive arm (a striking device with two degrees of freedom). (Image from my collaborator Wenhao Ding)
