I am currently a 2nd-year Ph.D. student in Electrical and Computer Engineering at UC, Riverside, co-advised by
Dr. Matthew J. Barth and
Dr. Guoyuan Wu. Before I started my Ph.D. study at UCR,
I received my Master's and Bachalor's degrees under the supervision of
Dr. Baigen Cai and Dr. Wei Shangguan at Beijing Jiaotong University.
My current research mainly focus on computer vision for enabling autonomous driving, e.g., 3D object detection, cooperative perception, multi-object tracking, etc.

MAJOR PROJECTS
Cyber Mobility Mirror (CMM)
Advisors: Dr. Guoyuan Wu, Dr. Xuewei Qi, Dr. Yongkang Liu, Dr. Kentaro Oguchi, Dr. Wei Matthew Barth
We focus on building a 3D reconstruction mirror in cyber world based on the perception information from traffic mobilities to support cooperative driving automation (CDA). My research mainly focus on object detection and cooperative perception, which are briefly introduced as follows:
- To propose 3D object detection, classification, tracking and reconstruction methods.
- To build up a real-time field operational system to perceive the traffic objects and distribute and display the reconstruction information for enabling CDA.
- To develop different simulation paltform to support various kinds of perception requirements and model training.
Reinforcement Learning Based Eco-Approach and Departure (EAD) System.
Advisors: Dr. Peng Hao, Dr. Guoyuan Wu, Prof. Wei Matthew Barth
My focus is to propose a RL-based eco-driving strategy under intersections with mixed traffic. My main contributions are shown as follows:
- Propose a reinforcement learning framework that can deal with logically complex driving task, such as passing a signalized intersection with mixed traffic.
- Design and Develop a Unity-based reinforcement learning simulator: signalized intersection scenario with CAVs and human-driven vehicles.
- Design a time-efficient and eco-friendly driving strategy for CAVs by combining vision data, on-board sensor data and V2I communication.
Intelligent Transportation Information Management System
Advisors: Prof. Baigen Cai, Prof. Wei Shangguan, Dr. Dakai Yang
A large-scale transportation information management project I worked on in 2018. My focus is to design and develop several software modules including applications and APIs. My main contributions are shown as follows:
- Designed and Developed Five Software Modules of the ITIMS including bus, taxi, intersection, traffic signal,s and flow detection modules
- Developed several high-reliable multi-source data API (Application Programming Interface) which connects to major transportation information database such as The Traffic Police Database in Zhuhai.
- Management and maintenance overall service infrastructure utilizing remote controller(Using Teamviewer, Xshell and Xftp), Oracle & Mysql database.
Machine Learning Based Autonomous Vehicle Control Methods
Advisors: Prof. Baigen Cai, Prof. Wei Shangguan, Dr. Linguo Chai
A large-scale heterougeneous traffic simulation project I am currently working since 2018. My focus is to explore robust and accurate control methods for CAV in heterougeneous traffic situations. My main contributions are shown as follows:
- Proposed a deep neural network called spatiotemporal LSTM to generalize the steering angle output by fitting in the raw image data.
- Proposed a deep Reinforcement Learning (deep RL) based high-level driving behavior decision-making algorithm.
- Developed a simulation environment based on the Unity3D Engine for the training and testing processes of the deep RL algorithm.
High-speed Railway Based BeiDou Fusion Positioning Performance Test
Advisors: Prof. Baigen Cai, Prof. Debiao Lu, Prof. Wei Jiang
A testing about the performance of the GPS, BeiDou and IMU fusion positioning under high-speed motion scenario (350km/h). My main contributions are shown as follows:
- Setup the test environment on the train and using device SPAN, UB380 recorded IMU and GPS/BeiDou information separately.
- Designed the automatic driving test scenarios based on site characteristics (such as the car-flowing scenario, overtaking scenario, obstacles recognition, etc).

China Railway Urumqi Railway Administration Group Co.,Ltd – Field Strength Test system
Advisors: Prof. Baigen Cai, Prof. Wei Shangguan
A Field Strength Test System project that I worked on my last year of Undergraduate (2017). The main purpose of the project is to design and develope a system to test, record, and analyze the wireless field strength along the railway. My main contributions are shown as follows:
- Design and developed a MFC framwork based windows software (about 15000 lines of C++ code) for the novel wireless field strength test (FST) system .
- Developed and tested the hardware system (collecting and packaging the sensor data such as ODO, GPS and TAX) of the FST system.
- Testing the whole FST system between Urumqi railway station and Akesu railway station (2018km in total).
