First-Year Ph.D. Student
The Ohio State University
I am a first-year Ph.D. student in the Department of Computer Science and Engineering at The Ohio State University, advised by Prof. Xiaodong Zhang. My research sits at the intersection of computer systems, GPU architecture, and high-performance computing, with a focus on using ray tracing (RT) cores, originally designed for graphics, to accelerate general-purpose computational workloads. I received my M.Eng. from Shandong University, where I was advised by Prof. Mengbai Xiao. I received my B.Eng. from Dalian Maritime University.

GPU RT Core Repurposing. Modern GPUs include dedicated RT cores for accelerating ray-triangle intersections and bounding volume hierarchy (BVH) traversals. My work investigates how these massively parallel spatial-query engines can be reprogrammed for graph algorithms, vector search, and scientific computing, workloads far beyond computer graphics.
Vector Search Acceleration. My work explores GPU-accelerated approximate nearest neighbor (ANN) search leveraging RT cores and GPU direct storage (GDS) techniques to scale to billion-scale datasets with low latency.
