Dr. Clarence A. Ellis is a Professor of Computer Science, and Director of the Collaboration Technology Research Group at the University of Colorado at Boulder. At Colorado, he is a member of the Systems Software Lab, and the Institute for Cognitive Science. During 1991, he was chief architect of the FlowPath workflow product of Bull S.A. Previously he was the head of the Groupware Research Group within the Software Technology Program at MCC. For the decade prior to joining MCC, he was a research scientist at Xerox Palo Alto Research Center.
Clarence (Skip) Ellis is on the editorial board of numerous journals, and has been an active instigator and leader of a number of computer associations and functions. He has been a member of the National Science Foundation Computer Science Advisory Board; of the University of Singapore ISS International Advisory Board; of the NSF Computer Science Education Committee; and chairman of the ACM Special Interest Group on Office Information Systems (SIGOIS). His interests include groupware, coordination theory, object oriented systems, CSCW, office systems, databases, distributed systems, software engineering, world-wide-web (internetworking), systems design and modeling, workflow systems, and humane interfaces to computers.
Dr. Ellis received his Ph.D. Degree in Computer Science from the University of Illinois where he worked on hardware, software, and applications of the Illiac 4 Supercomputer. After he graduated, he continued his work on supercomputers at Bell Telephone Laboratories. His dissertation was entitled "Probabilistic Languages and Automata," written under Professor David Muller.
Mr. Ellis has worked as a researcher and developer at Bell Telephone Laboratories, IBM, Xerox, Microelectronics and Computer Technology Corporation, Los Alamos Scientific Labs, and Argonne National Lab. His academic experience includes teaching at Stanford University, the University of Texas, MIT, Stevens Institute of Technology, and in Taiwan under an AFIPS overseas teaching fellowship. He has published several books, and over 100 technical papers and reports, lectured in more than a dozen countries, and was an invited speaker on object oriented systems at the most recent IFIP World Computer Conference.
