Home address: 2027 Parker St., Berkeley, CA 94704. (510) 848-7930.

Position:
Research scientist at ICIR since February 1999. (From 1999 through 2001 we were named ACIRI, the AT&T Center for Internet Research at ICSI.)
From May 1990 until January 1999, I was a member of the Network Research Group at Lawrence Berkeley National Laboratory.

Research interests:
Congestion control in computer networks, the analysis of network dynamics.

Specific areas of research have included the following:

TCP protocol changes (e.g., adding the Selective Acknowledgement Option to the TCP protocol standards, increasing the permitted initial window for TCP);
TCP traffic dynamics (phase effects, distribution of bandwidth among competing TCP connections);
The addition of Explicit Congestion Notification to the IP architecture;
Reliable multicast transport protocols (e.g., Scalable Reliable Multicast (SRM));
Router mechanisms for packet scheduling and for active queue management (Class-Based Queueing (CBQ), Random Early Detection (RED) queue management);
Equation-based congestion control mechanisms (TCP-Friendly Rate Control (TFRC)) for unicast streaming multimedia or for multicast traffic.
Datagram Congestion Control Protocol (DCCP), a transport protocol for unicast, unreliable transport.
Models for the evaluation of congestion control mechanisms.

All of this work has involved collaborations with other members of ICIR, of LBNL's Network Research Group, and with the wider networking research community.

Education:

Ph.D. in Computer Science, December 1989, and M.S. in Computer Science, May 1987, both from the University of California at Berkeley. Major field: theoretical computer science. Minor fields: statistics, mathematics.
Certificate in Electronics, May 1974, Merritt College.
B.A., December 1971, University of California at Berkeley. Major: sociology. Minor: mathematics.

Professional Experience:

Research Scientist at ICSI, February 1999 to the present.
Staff Scientist at Lawrence Berkeley Laboratory, December 1983 to January 1999. I began working in the Network Research Group in the summer of 1988, and then full-time starting in May 1990.
Teaching Assistant at UC Berkeley, summer 1987, and tutor for several years for the Computer Science Reentry Program at UC Berkeley.
Computer Specialist and Computer Systems Engineer for Bay Area Rapid Transit, April 1975 to September 1982. Design, maintenance, and repair for BART's real-time computer systems, including work on a joint BART-LBL project to design a replacement for BART's train control computer system.
