Singh's research interests include
multiagent systems,
service-oriented computing,
software engineering,
artificial intelligence, and
social networks. He has made several important contributions to the understanding of interaction and norms in multiagent systems. He introduced to artificial intelligence the distinction between social commitment (a norm) and psychological commitment (a mental attitude). Singh also introduced the idea that interaction among autonomous social principals (e.g., between two or more organizations) must have a social semantics. This idea has proved to be highly influential within multiagent systems research. In recognition of Singh's contribution, the paper in which he introduced this idea was awarded the IFAAMAS 2016 Influential Paper Award. Taking this line of thinking further, Singh, in joint work with his Ph.D. student
pInar Yolum, introduced the abstraction of commitment protocols. Singh has also made important contributions to social networks, trust, and distributed computing. His Blindingly Simple Protocol Language (BSPL) introduces the idea that message ordering in interaction protocols fall out automatically from information flow requirements. Therefore, one need not model specify control flow at all in interaction protocols. ==References==
