Yitzhak "Tsahi" Birk heads the Parallel Systems Lab at the TN-IIS partner Technion in Haifa, Israel. His research interests include computer systems and subsystems, as well as communication networks. He is particularly interested in parallel and distributed architectures for information systems, including communication-intensive storage systems (e.g., multimedia servers) and satellite-based systems, with special attention to the true application requirements in each case. The judicious exploitation of redundancy for performance enhancement in these contexts has been the subject of much of his recent work. He is also engaged in research into various facets of processor architecture, attempting “cross fertilization” between his various areas of research.
