About Me

I am a PhD student at School of Computer Engineering (SCE) and Institute of Media Innovation at Nanyang Technological University, under the supervision of Assistant Professor Jie Zhang and Professor Nadia Magnenat-Thalmann. I received my Masters in Software Engineering from National University Of Singapore and Bachelors in Computer Science and Engineering from Pondicherry Engineering College, India. Here is my CV (PDF).

Research Interests

Trust and Reputation Management: I focus on trust systems for e-commerce and wireless sensor networks. My main research is to deal with robustness issues in trust systems by mitigating unfair rating attacks

Artificial Intelligence-Multi-Agent Systems: Intelligent decision making and planning under uncertainty. We model e-marketplaces with buying and selling agents and develop trust systems to assist buyers in selecting quality sellers. We use artificial intelligence techniques to compute the trust scores of the agents and also use planning approaches like POMDPs for decision making
