About Me

Hi, I’m Liang Geng (耿亮), a third-year Ph.D. student in the Computer Science Department, OSU. I’m interested in computer systems, especially GPU and RDMA programming. My current research is repurposing NVIDIA RT Cores to accelerate non-graphics workloads, such as geospatial data processing. My advisors are Prof. Xiaodong Zhang and Dr. Rubao Lee. Before joining the OSU, I was a senior engineer at Alibaba DAMO Academy supervised by Dr. Wenyuan Yu, where I developed GPU support for libgrape-lite and was the initial contributor to GrapeScope and Vineyard. I was fortunately advised by Prof. Yanfeng Zhang and Dr. Hao Wang while pursuing my Master’s Degree. They helped me to start my research journey.
