I am interested in machine learning, computational neuroscience, cognitive psychology and neuropsychopharmacology (among other things). More detailed descriptions will come soon; in the meantime, please take a look at my publications.

Brain-Computer Interfaces

For my doctoral thesis, I worked on the topic of Brain-computer interfaces. The goal is to use the tiny electrical signals generated by the brain (measured via a variety of invasive and noninvasive methods) to directly communicate with the external world. In the course of my graduate career, I investigated various aspects of the brain-computer interface scenario: (1) the interpretation problem, consisting of signal processing, feature selection, classification and tracking to extract information from the brain, (2) the interface problem, where we consider a variety of ways to translate this information into an effective user interface for controlling devices or communicating information, and (3) the behavior modelling aspect, where we examine and exploit models describing the user's behavior (including learning and adaptation).

Research History

Here are some of the research groups I have worked with:

• Cognitive Science Department at the University of California, San Diego.
• Neural Systems Laboratory at the University of Washington.
• VIBE Lab at Microsoft Research.
• Intelligent Data Analysis group at Fraunhofer FIRST, Berlin Germany.
• Database Group at the University of Washington.
• Information Sciences Dept. at Bell Laboratories, New Jersey.
• Database Group at the Indian Institute of Technology, Bombay.
• Database Lab at the Indian Institute of Science, Bangalore.
• Tata Institute of Fundamental Research, Bombay.

I worked for a while in database research. just because... Topics included XML data manipulation -- in particular, indexing and relational exchange of XML data. This was work I did at Bell Laboratories. (Sadly, the group I worked with there no longer exists). I have also worked on problems in corpus-based schema integration, traditional query optimization, query result caching and association rule mining.
