Assistant Professor, College of Engineering Professor in Charge, Manufacturing Processes Laboratory: University of Wisconsin-Milwaukee, Milwaukee, Wisconsin 53201 Researched in the areas of computer-integrated manufacturing and flexible manufacturing systems. Also designed and developed a new robotic arm. Implemented a new technique using successive screw displacement for determining displacements, Jacobian surfaces, working volumes, and voids and holes in working volumes of industrial robots. Elaborated an algorithm for finding workspace of any robot that contains any combination of revolute and prismatic joints. Developed a computer program for plotting the workspace.
Assistant Professor College of Engineering Old Dominion University, Norfolk, Virginia 23508 Proposed a new theory that in metalworking, strain rate has significant effects on normal and shear stress distributions. Modified and applied dynamic visioplasticity technique, which enables the complete stress history of any steady or nonsteady, quasi-static or impact, plane strain plastic deformation process to be determined from a record of the deformation pattern. It is a very useful tool for studying metalworking problems.
