My research centres around the making of data-intensive systems that are fast, cost-effective and energy-efficient, in the context of persistent memory, massively parallel processors and next-generation networks. Sometimes I step into related areas such as parallel programming and operating systems while solving problems in database systems. I also have interests in embedded and mobile systems. My recent focus is on concurrency, indexing and parallel programming on persistent memory.

I am part of the Systems Group and the Data Science Research Group at SFU. If you would like to schedule a meeting with me, please check my calendar.


Dec 18, 2019: Interested in knowing how database indexes perform on actual Intel Optane DC Persistent Memory after more than a decade of emulation based research? Check out our recent VLDB paper! We have also released an open-source tool (PiBench) for bechmarking persistent memory indexes.

Nov 30, 2019: I received the IEEE TCSC Award for Excellence in Scalable Computing (Early Career Researchers) for contributions to scalable data processing.
