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.
