About Me
I am a Professor in the Computer Science Department of University of California, Los Angeles. In 2017, I worked at Microsoft Research as a Visiting Researcher where I created and led the development of a project that built an optimizing compiler (Niijima, SOSP'19) for Microsoft's Scope/Cosmos, a multilingual data analytics pipeline. I worked at IBM T. J. Waston Research Center as a Co-op/intern from 2008 to 2011 where I led the development of a series of runtime bloat detection/performance optimization tools for IBM's enterprise Java customers (PLDI'09, PLDI'10-a, PLDI'10-b).
My research is in the general area of computer systems, ranging from programming languages and compilers, to runtime/operating/distributed systems and computer architecture. My current focus is on two areas: (1) infrastructures for future cloud computing (in particular, user-defined cloud) and (2) infrastructures that provide cheap scalability for ML applications (i.e., affordable AI).
I was one of the first academic researchers working on the problem of ``software bloat'', which eventually led to ONR's TPCP program. I also spearheaded the direction of optimizing large-scale data analytics with PL techniques. Our Yak GC (OSDI'16) was reimplemented and used by Huawei to power their telecommunication applications. Due to these contributions, I was awarded the 2018 Dahl-Nygaard Junior Prize, which is awarded each year to a junior researcher that has made promising contributions to the field of object orientation.
