Short Bio
I'm current a PhD candidate at MIT, CSAIL, Data System Group.
I'm super fortunately co-advised by Prof. Samuel Madden and Prof. Tim Kraska.
Before MIT, I achieved a master degree from University of Oxford and bachelor degrees from Carnegie Mellon University.
My research focus is on query optimization and query processing.
I'm also working on hybrid transactional and analytical processing system (HTAP).
