Joined department in 1998

Dr. Prabhakar's research focuses on performance and privacy issues in large-scale, modern database applications such as multimedia, moving-object, and sensor databases. The efficient execution of I/O is a critical problem for these applications. The scope of this research ranges from main memory to disks and tertiary storage devices. Sensor and moving object applications are also faced with the need to process large volumes of data in an online manner. The current research effort addresses efficient continuous query evaluation and novel techniques for managing the inherent lack of accuracy for these applications. Dr. Prabhakar's interest also lies in the design and development of private databases and digital watermarking techniques for structured (e.g. relational databases) and semi-structured (e.g., XML) data. He is also working on developing advanced databases for biological data. His current focus is on developing a transparent and reliable protein function database. Prior to joining Purdue, Dr. Prabhakar held a position with Tata Unisys Ltd. from 1990 to 1994.
