Professor Denis Trapido joined the Merage School of Business in 2008. His research focuses on the effects of competition on the formation of social and economic ties, the origins and rewards of creativity, and the evolution of professional networks. His work has examined a variety of professional communities, including the venture capital industry, academic disciplines, and communities of maritime merchants in 18th century Europe. His fieldwork in the San Francisco Bay Area, supported by the National Science Foundation, has mapped the networks of competition and interorganizational ties among two thirds of the active drug development companies in the region. Professor Trapido’s research has appeared in Organization Science, American Journal of Sociology, Social Forces, and European Sociological Review. He has also contributed book chapters and published wider-interest interdisciplinary work.
