关于
I am a researcher in the Data Systems group (previously DMX) at Microsoft Research, Redmond with interests in database systems and analytics.
My current focus is on query optimization and database tuning, spanning sub-areas such as:
- query optimization and execution of imperative code in database systems.
- workload management and characterization techniques, e.g., workload compression, workload forecasting, and workload simplification/reduction.
- ML for scalable index tuning and cost modeling.
Prior to joining MSR, I completed my Ph.D. from the University of Illinois at Urbana, Champaign (UIUC), advised by Aditya Parameswaran.
