About the Author :
David G. Messerschmitt is the Roger A. Strauch Chaired Professor of Electrical Engineering and Computer Sciences at the University of California at Berkeley. From 1993-96 he served as Chair of EECS, and prior to 1977 he was with AT&T Bell Laboratories in Holmdel, N.J. He received a Ph.D. from the University of Michigan, is a Fellow of the Institute of Electrical and Electronic Engineers, a member of the National Academy of Engineering, and is the 1999 recipient of the IEEE Alexander Graham Bell Medal recognizing "exceptional contributions to the advancement of communication sciences and engineering". Messerschmitt's current research interests include wireless access to packet networks, network management, the role of mobile code in network infrastructure, the convergence of computing and communications, and the economics of networks. Messerschmitt is active in new curriculum development bringing highly relevant social science concepts to engineering students and educating a broader crossection of students in information technology. He has initiated both undergraduate and graduate courses in networked applications and computing aimed at social science and business students, and Networked Applications is an outgrowth of this effort. With Hal R. Varian, he also initated a graduate course in the non-technical factors contributing strongly to the success or failure of new high-technology products. Networked Applications is also used in this course, which is taught to a mixture of engineering and business students. Messerschmitt is a co-founder and Director of TCSI Corporation, and a Director of Coastcom Inc. He is on the Advisory Board of the Fisher Center for Management & Information Technology in the Haas School of Business, the Kawasaki Berkeley Concepts Research Center, and the Directorate for Computer and Information Sciences and Engineering at the National Science Foundation. In the University of California Academic Senate, he is a member of the Representative Assembly and an elected member of the Berkeley Divisional Council. From 1993-98 he was a Member of the Computer Sciences and Telecommunications Board (CSTB) of the National Research Council (NRC), and he is currently co-chairing an NRC study on the future of information technology research.
