I am a Senior Lecturer in Artificial Intelligence in the School of Computer Science at the University of Bristol (UoB). My research interests are in AI, socially intelligent agents, and multiagent systems with an emphasis on ethics, cybersecurity, and privacy.

I received a Ph.D. and an M.S. in Computer Science from North Carolina State University, and a B.E. in Computer Engineering from Sardar Vallabhbhai Patel Institute of Technology, Gujarat University. My doctoral dissertation was advised by Professor Munindar P. Singh.

Prior to joining Bristol, I was a Postdoctoral Research Scholar in Computer Science at North Carolina State University, supported by NSA Science of Security Lablet. I was advised by Professor Munindar P. Singh and Professor Laurie Williams. I worked in the Multiagent Systems and Social AI Lab and with the Realsearch Group.

In Fall 2017, I worked as research intern with the CTO research team of HERE Technologies. At HERE, I built location and trajectory privacy-preserving data publishing, query answering, and learning systems. From 2007 to 2012, I worked as a researcher in the Software Engineering Lab at Tata Research Development and Design Centre (TRDDC), India. At TRDDC, I worked on agile requirements engineering, social software and semantic web, and knowledge extraction, representation, reuse and reasoning. My research focused on making available domain knowledge (tacit as well as explicit) visible and accessible, so as to make it amenable for reconfiguration and reuse.
