I work to create IT systems that push beyond the boundaries of what is typically possible today to allow us to solve problems that are beyond the reach of our current tools. Currently I am working to create IT systems which are most suitable for cognitive and big data applications. My work experience covers the design, creation and operation of very large, often distributed, computing systems. Early work includes the Andrew System (AFS, ATK) & DFS. I designed and managed the operational aspects of the largest SP computing system in IBM from 1995 to 2000. I designed & build the prototype system for GSA distributed storage sytesm and designed and implemented of the low-level control and monitoring subsystem for Blue Gene/L and Blue Gene/P.
