I am a senior researcher and manager in Data&AI department of IBM Research at Bangalore. 

My research interest includes Artificial Intelligence, Natural Language Processing, Knowledge representation, Program Analysis, Security, Software Debugging, Testing, Verification, and Programming Languages.  My current focus is on building dependable AI systems using bias and adversarial AI testing, debugging, and verification. I am also 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.


I received my Ph.D. 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.
