Dr. K. K. Ramakrishnan is a Professor in the Dept. of Computer Science and Engineering at UCR. He was most recently a Distinguished Member of Technical Staff at AT&T Labs-Research, and has been recognized for his fundamental contributions on communication networks including his work on congestion control, traffic management and VPN services. He has created innovative network solutions that are efficient and robust, working at large scale. K. K. has published over 200 papers and has 144 patents issued in his name. Prior to 1994, he was a Technical Director and Consulting Engineer in Networking at Digital Equipment Corporation. Between 2000 and 2002, he was at TeraOptic Networks, Inc., as Founder and Vice President. He is on the editorial board of several journals in Networking. He has served as the TPC Chair and General Chair for most of the major conferences on computer networks and was a member of the National Research Council Panel on Information Technology for NIST. He currently serves as the Steering Committee Chair for IEEE ICNP.
