Sergio Takeo Kofuji is assistant professor at the Electronic Engineering Department of the Engineering School of the University of Sao Paulo, Brazil, and the head of the Digital System Division of the Integrated System Laboratory. He is interested in high performance computing architectures and networks, including parallel architectures, FPGA architectures, VLSI systems design, and high speed computer networks. The focus of his research is shared memory scalable parallel architectures based on commodity workstations and point-to-point high speed low latency links and switches. Currently coordinates a multigroup Project aiming to design and implement a heterogeneous parallel system based on workstations, ATM links and switches, and SCI based cache coherence protocols.
