Short Bio

Chris Dellarocas teaches Information Systems at the Robert H. Smith School of Business at the University of Maryland. He holds Ph.D. and M.S. degrees in Computer Science from MIT and a Diploma in Electrical Engineering from the National Technical University of Athens. His research lies at the intersection between information systems, economics, and policy. The focus of his work is the study of the rapidly growing online "word-of-mouth" communities and their impact on marketing, product development, and public opinion formation. He also studies the use of online reputation mechanisms as a low-cost trust building device in electronic markets. Before joining the Smith School, Prof. Dellarocas taught at MIT's Sloan School of Management. He has also worked as an IT consultant for Andersen (now Accenture) and McKinsey. He is an inventor with 3 patents and the co-founder of one software company.
