Prof. Dr. Hugo de Garis

Head of "UTAH-BRAIN Project"

Utah State University's Artificial Brain Project

Prof. Hugo de Garis has been the Economist Magazine's "World Technology Award" Finalist (1999). In 2000, he obtained US$1 million grant from Brussels Government to build an Artificial Brain, and, in 2001, his artificial brain was recorded in the Guinness Book of World Records "Most Complex Brain Building Machine" (p126, 2001). He obtained a B.Sc. (Hons) in Applied Mathematics and Theoretical Physics at Melbourne University, Victoria, Australia, in 1970. He moved to the UK where he was a supervisor (instructor) to the mathematics undergraduates of Cambridge University for 4 years. He then joined Philips in Holland and Belgium as a software and hardware architect, covering most branches of computer science. Growing discontent with industry, he switched careers to do research at Brussels University, where he finished a PhD in Artificial Intelligence and Artificial Life. Prof. Dr. de Garis has published some 70 journal/conference papers and book chapters.

From February 1993 to January 2000, de Garis was the head of the Brain Builder Group in the Evolutionary Systems Department at ATR Labs in Kyoto, Japan. The aim was to use Cellular Automata Machines (CAMs) to grow/evolve a 75 million neuron (64K module) artificial brain at electronic speeds, using state of the art evolvable hardware (Xilinx XC6264 FPGA chips) which can update CA cells at over 130 Billion a second, and evolve neural network modules in about a second. The name of this research effort was the "CAM-Brain Project". It is de Garis's ambition to see the building of artificial brains grow into a major effort equivalent to America's NASA moon shot.

From Sept 2001, Dr. de Garis has been an associate professor of computer science at Utah State University (USU), Logan, Utah, USA, teaching the planet's first (M.Sc./PhD) course in "Brain Building", and another new course, "Frontiers of Computing" (quantum computing, reversible computing, nanotechnology, DNA computing, membrane computing, quantum dots, molecular computing, etc). He aims to build a new generation of brain building machine and an artificial brain, each 5 years or so. He is currently looking for funding towards these goals. Prof. de Garis is setting up a "Brain Building Center" at USU, consisting of researchers, students, professors, and commercial interests (May 2002, 11 people so far).

Prof. Graham Megson

Director of the High Performance Computing Centre

Computer Science Department, The University of Reading

Prof. Graham Megson has been the Professor of Computer Science at the University of Reading since 1995. He was Head of Department from 1997-98, and Head of Parallel Emergent and Distributed Architectures Laboratory (PEDAL) at Reading and has enjoyed significant funding from Newcastle University. From 1990-1995 he co-ordinated the University funded Strategic Research Initiative on Parallel Algorithms Research, Newcastle University. From 1995 - present has been the director of the High Performance Computing Centre (HPCC, a facility of over UKP 1M), at the University of Reading. His work has led to numerous innovative systolic algorithms and the development of the first systematic synthesis method for mapping classes of dynamic (or run-time) dependencies onto regular arrays. Synthesis Tools have been incorporated into the public domain version of MMAlpha. He has solved a number of open mapping problems in the areas of dynamic programming and combinatorial optimization, and in connection with Honeycomb tori as well as designing numerous application specific algorithms. His current interests centre on the development of systematic methods for mapping and scheduling computations on to parallel architectures encompassing the analysis and design of regular parallel algorithms, massively parallel, Field Programmable Gate Arrays, as well as Neural Networks and Genetic Algorithms.

Professor G.M. Megson (BSc(Hons), PhD, CEng, MBCS) was awarded a BSc(Hons) Class I in computational science from Leeds University in 1984. After a period of postgraduate research, at Loughborough University, in 1987 he recieved a PhD for work in systolic algorithm design. In July 1987 he was appointed as the ATLAS Research Fellow at Rutherford Appleton Laboratory (RAL) and simultaneously held a Junior Fellowship of Oriel College, Oxford University. Prof. Graham Megson is a member of the BCS, has served on over 10 Programme Committees for international conferences. He has been a member of the IEEE technical committee on computer architecture, the EPSRC review college for the system architectures committee, and currently served on the AWE Supercomputing Panel. He is editor-in-chief of the Journal Parallel Algorithms and Applications (1997-), and edits an international book series on parallel computing. He has published over 130 papers at international conferences in journals including five books on systolic algorithms/architectures and related topics.
