Ramayya Krishnan is the W. W. Cooper and Ruth F. Cooper Professor of Management Science and Information Systems at the H. John Heinz III College and the Department of Engineering and Public Policy at Carnegie Mellon University. A faculty member at CMU since 1988, Krishnan was appointed Dean when the Heinz College was created in 2008. He was reappointed upon the completion of his first term as Dean in 2014.

Krishnan was educated at the Indian Institute of Technology and the University of Texas at Austin. He has a Bachelor’s degree in mechanical engineering, a Master’s degree in industrial engineering and operations research, and a PhD in Management Science and Information Systems. Krishnan’s research interests focus on consumer and social behavior in digitally instrumented environments. His work has addressed technical, policy and business problems that arise in these contexts and he has published extensively on these topics. He has served as Department Editor for Information Systems at Management Science, the premier journal of the Operations Research and Management Science Community. Krishnan is an INFORMS Fellow, a member of the Global Agenda Council on Data Driven Development of the World Economic Forum, and a former President of the INFORMS Information Systems Society and the INFORMS Computing Society. He is the recipient of the prestigious Y. Nayuduamma award in 2015 for his contributions to telecommunications management and business technology. Krishnan was a co-leader of the recently concluded strategic planning exercise at CMU focusing on the transformative CMU experience for students, faculty and staff.

Krishnan’s government service include his current work on the IT and Services Advisory Board chaired by Gov. Tom Wolf of the State of Pennsylvania. He has served as an Information Technology and Data Science expert member of multiple US State Department Delegations and briefed ICT ministers of ASEAN in October 2014 on big data technology and policy.

Krishnan’s leadership experience include his founding of the information systems and management program at Carnegie Mellon and his term as the First Dean of the Heinz College, a unique college that is home to both the Public Policy School and Information Systems School at Carnegie Mellon. This unique co-location of information technology, public policy and management brings together a multi-disciplinary faculty consisting of data scientists, social scientists, engineers and information technologists dedicated to educating “men and women of intelligent action.” Faculty and students address important societal issues increasingly being transformed via developments in information technology in domains such as information privacy and intellectual property, health care delivery and health care markets, and consumer behavior. The College’s global footprint in the US (Pittsburgh and Washington D.C.), in Singapore and in Adelaide, Australia enable these issues to be addressed from a global point of view and using international testbeds.

Krishnan led the establishment of research centers focused on data driven decision making in key societal domains including transportation, smart cities, and living analytics. He has participated in the World Economic Forum and a summary of his ideaslab presentation is at http://goo.gl/IqkMKR. A recent interview on Big Data with NDTV is at http://goo.gl/WyxEi3.

Krishnan’s recent participation in discussions around big data and smart cities as a leader of CMU program on integrated intelligence held in India can be found at http://www.cmu.edu/news/stories/archives/2015/july/the-next-digital-frontier.html and a compilation of relevant media reports on Living Analytics, a center co-founded by Krishnan, is at http://centres.smu.edu.sg/larc/media-reports/.
