Dr. P. Venkat Rangan

Vice Chancellor · Amrita Vishwa Vidyapeetham

Dr. P. Venkat Rangan is an internationally recognized pioneer of research in Multimedia Systems and Internet E-Commerce, and the founding Vice Chancellor of Amrita Vishwa Vidyapeetham. In this role he has established more than 50 research centers and architected over 500 international collaborations, driving the University to top-ranking positions with both national and international ranking agencies.

Earlier, Dr. Rangan founded and directed the Multimedia Laboratory at the University of California, San Diego (UCSD), where he served as a Professor of Computer Science and Engineering for 16 years. In 1996 he became one of the youngest faculty members ever awarded a Full Professorship in the University of California system — just seven years after earning his Ph.D. from U.C. Berkeley in 1989. He has authored over 125 publications in international journals and conferences (chiefly IEEE and ACM) and holds 40+ U.S. patents.

In 1993, Dr. Rangan founded the first International Conference on Multimedia — ACM Multimedia ’93 — serving as its Program Chairman; it remains the premier worldwide conference on multimedia. He also served as the founding Editor-in-Chief of the first international ACM Journal on Multimedia, now the premier journal in the field. Several startups emerged from his Multimedia Lab, including the San Diego–based Intervu (1995) and InnovaTV (1997), early pioneers of Internet video streaming.

In 1999, Dr. Rangan founded Yodlee, built on his innovation of Internet Information Agents, with investment from Sequoia Capital. As its CEO, he took the company to an IPO at a $600 million valuation. In July 2000, Internet World featured him on its cover and named him one of the top 25 Stars of Internet Technologies.

Dr. Rangan has also served as a member of the multimedia expert panel of the U.S. National Academy of Sciences, a visiting scientist at Xerox PARC, Multimedia Technology Advisor to the Electronics Secretary of the Government of India, and Program Chairman of the 1997 Indo–US Bilateral Conference on Multimedia.

Education

Dr. Rangan obtained his Ph.D. in Computer Science from U.C. Berkeley in 1989; in 1988 his Berkeley doctoral thesis was judged the outstanding Ph.D. of the year by IBM. He earned his B.Tech. in Electronics from the Indian Institute of Technology, Madras in 1984, where he received the President of India’s Gold Medal.

Mentorship & Legacy

Dr. Rangan has trained numerous students who now contribute significantly across India and the world. His first doctoral student is today the global CTO of India’s largest software company. He has mentored several Deans at Amrita to build Centers of Excellence in strategic fields of science, technology, medicine and AI. His first doctoral student from Amrita currently serves as Provost of Research and is also listed among Stanford University’s top 2% of scientists.
