Research Interests

My research broadly spans systems software, with a primary focus on database systems. I design hardware-aware execution and data-movement mechanisms for heterogeneous platforms, ranging from GPU-, PIM-, and DPU-accelerated servers to resource-constrained and trusted edge devices.

My goal is to translate emerging hardware capabilities into practical, efficient, and secure end-to-end systems.

• Systems software, with an emphasis on database systems
• GPU-accelerated analytical and out-of-memory query execution
