About Me

I am a postdoctoral associate at the MIT Data Systems Group and an NSF/CRA Computing Innovation Fellow, working with Tim Kraska and Michael Cafarella. I build the next generation of machine learning-empowered data management, processing and analysis systems. My research focuses on deeply understanding both machine learning and systems techniques, resulting in entirely new designs, algorithms, and data structures for data-intensive systems and applications. My research areas broadly include instance-optimized database systems, scalable knowledge base construction, big spatial data management and analysis, and data processing in containerization environments.

Before joining MIT, I completed my PhD in computer science from University of Minnesota, Twin Cities under the supervision of Mohamed F. Mokbel. My PhD work recieved the University-wide Best Doctoral Dissertation Honorable Mention, and the prestigious Doctoral Dissertation Fellowship (DDF) from University of Minnesota. I was also awarded the first place (gold medal) of the graduate student research competition (SRC) in ACM SIGSPATIAL 2019, and the best paper runner-up in ACM SIGSPATIAL 2018. I have also collaborated with many researchers from Microsoft Research, NEC Labs America, Harvard University, and Technical University of Munich.

I am currently in the academic job market. Please reach out to me, if you are hiring. Here is my CV.
