Prof. Chellappa’s current research focuses on economic, behavioral and technical aspects of electronic markets.  In particular, his research aims to understand how the adoption of the Internet by both consumers and vendors has changed conventional views of products and business transactions.  His recent research includes:

Pricing for Platforms and Electronic Markets

Pricing and Piracy of digital goods

Personalization and Privacy issues in online markets

Information technology standards and its role in shaping competition and alliance formation

Cloud Computing

The first known academic usage and definition of the term Cloud Computing appears to be provided by Prof. Chellappa in a talk titled Intermediaries in Cloud-Computing, presented at the INFORMS meeting in Dallas in 1997.

He suggested that this would be a new “computing paradigm where the boundaries of computing will be determined by economic rationale rather than technical limits alone.
A follow-up research in 2002 refers to this definition and proposes pricing models specifically for active intranets.
