About
I am a researcher in the Data Systems group at Microsoft Research, Redmond.
My research interest lies in improving the performance of database systems with focus on:
- Query Optimization. Check out my recent work in this area:
- Database Tuning. Recent work includes:
- Scalable index tuning using ML techniques: Filtering and costing configurations, Efficiently searching configurations
- Workload compression for index tuning
- Workload forecasting
My research has been awarded with the best paper at ACM SIGMOD, Research Highlight, as well as featured in CACM. Prior to joining MSR, I completed my Ph.D. from the University of Illinois at Urbana, Champaign (UIUC), advised by Aditya Parameswaran.
