I am a first-year PhD student in the Computer Engineering Lab (CEL) at the University of Sydney, advised by Prof. Philip Leong. My research interests include computer architecture and FPGAs, with a focus on LLM accelerators and agentic EDA.
Before coming to USYD, I spent a wonderful time in Canberra for Master of Computing (Advanced) degree at the Australian National University from 2024 to 2025. I received a Bachelor's degree in Computer Science and Technology from Beijing Institute of Technology in 2022.
I am open to internship opportunities, collaborative research, technical discussions, and knowledge-sharing opportunities in computer architecture, FPGA acceleration, LLM accelerators, and design automation across academia and industry.

Matrix multiplication is a fundamental kernel in large-scale artificial intelligence and scientific computing, but its performance on conventional electronic accelerators is increasingly constrained by memory bandwidth and energy efficiency. Photonic computing offers a promising alternative due to its ultra-high bandwidth, massive parallelism, and low power dissipation. However, most existing photonic systems are limited to low-precision computation because of analog optical modulation constraints and noise accumulation, which restricts their applicability in precision-critical workloads. To address this limitation, we propose LightMat-HP, a hybrid photonic-electronic computing system that enables end-to-end acceleration of general matrix multiplication with configurable computational precision. LightMat-HP adopts...

This paper introduces a novel online data-driven methodology for risk assessment in human-robot interaction scenarios. Traditional risk assessment techniques relying on the Hamilton-Jacobi-Isaacs (HJI) method are computationally intensive and require offline calculations. To overcome these limitations, the proposed approach leverages neural networks to predict control actions and construct an augmented dynamic model. The model then utilizes the HJI method to predict the Forward Reachable Set (FRS) for risk assessment. This approach addresses the challenges…

To detect the cone of the Formula Student Autonomous China (FSAC) track quickly and accurately, this paper proposed a fast and accurate perception system that fused the 3D LIDAR point cloud data and visual information. First, the vision part spliced the images of the two monocular cameras vertically and adopted the YOLOv3 target detection network with the attention mechanism to obtain the type of candidate targets and their position on the pixel plane. Afterward, the track boundary could be extracted and the drivable area could be segmented using cubic polynomial regression by the center of the bounding box. The LIDAR pipeline used the GPF algorithm and the Euclidean clustering algorithm to process the original point cloud to obtain the three-dimensional information of the cones’ coordinates. Finally, the 3D LIDAR point cloud data of reconstructed cones was projected onto the two-dimensional pixel plane …
