Research Interests
My research interests are in the following:
- Architectural support for system softwares: both native and virtualized.
- The virtual memory system and address translation, cache and memory systems.
- Virtual memory system and address translation for emerging memory systems such as stacked DRAM and NVRAM.
- Virtual memory system for I/O devices (NVMe, Network, etc.) and Accelerators (GPUs, NPUs, etc.)
