I work in the database group at IBM Almaden on high performance data management. I started the Blink (now BLU) research project on query processing over compressed data, that has now been productized as DB2 with BLU Acceleration, and also the Informix Warehouse Accelerator. Previously I worked on adaptive and interactive query processing and on data cleansing.
Before joining IBM, I studied under Prof. Joseph M. Hellerstein at University of California, Berkeley for my Ph.D, and before that at IIT Madras.
