I am a senior researcher in Cognitive Solutions and Services department of IBM Research at Bangalore. I received my PhD degree in Computer Science from the State University of New York at Stony Brook. My advisors were Prof. C. R. Ramakrishnan and Prof. Scott A. Smolka. I received my B.E. degree in Computer Science and Engineering from Jadavpur University. Prior to joining IBM Research, I have worked with Motorola India Research Lab at Bangalore and Interra IT at Noida.

My research interest includes Natural Language Processing, Knowledge representation, Program Analysis, Security, Software Verification, and Programming Languages.  My current focus is on building natural language dialogue systems for cognitive interaction with structured and unstructured data. My past projects in IBM are related to Automated Fault Localization, Program Repair, Program Equivalence, Program Refactoring, Program Tracing and Profiling, Program Migration/Translation, API Extraction, and Grammar Inference.
