My research interests are in the general area of embedded systems architectures.  My interests are driven from a systems perspective, looking at the definition, design, and interactions of programming languages, run time system software and hardware components within a complete system architecture framework.  Lately I have been focused on developing new computational models to support and enable the familiar thread programming model for hybrid systems:  systems with both general purpose CPU's as well as reconfigurable components.  I am also investigating new computation/communication architectures for sensor web systems.  I continue to be interested in general purpose parallel and distributed computing architectures, and am trying to bring some of my interests together by investigating the application of embedded systems techniques into the general purpose computing world.  We'll see.....
