When I am not doing research, I'm probably traveling with friends, or playing different types of sports including but not limited to Soccer, Volleyball, Hiking, and Biking, or exploring Boston restaurants trying new foods! I also spend time on reading self-development books, cooking, watching documentaries and standup comedies, and some other hobbies!

Our paper (Peafowl) got accepted in ACM Symposium on Cloud Computing 2020 (SoCC '2020)


May, 2020

I am so excited to announce that I will be joining MIT's Tim Kraska at einblick.ai for a summer internship on database systems.


Febraury - 2019

Our paper (Yawn) got accepted in ACM Asia Pacific Workshop on Systems (APSYS 19)


About Me

I am a computer systems researcher. My research interests are in the areas of big data, data streams and systems software, focusing on designing efficient computer systems for big data and stream processing.
My research improves the performance, cost, and energy efficiency of database systems. I have designed and implemented practical and scalable systems that improve performance and energy-efficiency of modern database systems.

    Internships

    Einblick-Summer 2020
    Einblick is an MIT-based startup founded by Tim Kraska . Einblick is powered by an in-memory analytics engine developed out of MIT and Brown University academic research. Einblick allows data scientists to significantly more quickly build accurate high performance models, and make them available to decision makers.
    In Einblick, I was researching an OLAP architecture that tries to process data mostly in the cache (i.e., in-cache execution). In other words, this architecture should have avoided expensive memory accesses as much as possible when processing in-memory data. Over my time in Einblick, I designed a new architecture based on the Arrow framework for in-cache execution of queries like hash aggregation and build it over the summer. Our experiments showed the new architecture was up four times faster. The main reason for this speed-up was significant lower cache misses in our new architecture.
