PhD student working under the guidance of Prof. Ada Gavrilovska. My interested research areas include Operating systems -- in particular the memory subsystem. In my recent projects I have looked in to developing efficient system software abstractions for main memory and persistent memory(NVM) devices, with keen interest on topics such as fault-tolerance and memory-consistency.

I finished my PhD studies and joined Meta's AI-infra org focusing AI trainer fault tolerance topics.
