I am currently a research scientist at the Database Systems Group, IBM Research Almaden (manager: Fatma Ozcan). My job is to design and implement distributed database management systems for high throughput transaction processing and real-time analytics in the cloud.
I received my Ph.D. degree in 2017 from National University of Singapore, where I was affiliated with the Database Group (advisor: Kian-Lee Tan). Previously, I was a visiting Ph.D. student at the Database Group, Carnegie Mellon University (host advisor: Andrew Pavlo), a research intern at the System Group, Microsoft Research Asia, and a research intern at the Cloud Infrastructure Group, EMC Labs China. I earned my bachelor's degree from South China University of Technology in 2012.
I have particular interests in exploiting modern hardware (e.g., highly parallel CPU/GPU, hierarchical storage) and low-level optimizations (e.g., code generation) to build ridiculously fast intelligent systems. I am enthusiastic to integrate research into real-world systems. I am a developer of a commercial DBMS product, IBM Db2 Event Store, and a key developer of two DBMS prototypes, namely Peloton and Cavalia. I was also a contributor to Apache Flink.
I am glad to review database/systems-related research papers!
