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 & address translation for emerging memory systems such as stacked DRAM and NVRAM.
  • Improving TLB shoot downs on state of art systems, and TLB organization on GPUs and Accelerators.

My CV is available here
