After receiving my MS from Technical University of Gdansk, Poland and my PhD from the University of Delaware in mechanical engineering, I joined the staff at Widener University, where I currently serves as a senior lecturer in the mechanical engineering department.
My areas of expertise and research interests are in applied lubrication theory, bearings, tribology, rotor dynamics, and renewable energy.
My current work at Widener focuses in two areas: (1) Teaching a range of courses in the fluid-thermal area, and (2) Coordinating and teaching the first engineering course, ENGR 111 Engineering Techniques, for engineering freshmen.
I am interested in the research and development of bearing systems, seals, and dampers that will lead to energy efficiency and other improvements of turbomachinery. I am especially interested in compliant foil bearings and the applications where they can provide a major technological leap, such as oil-free propulsion, small turbomachinery, and ultra-high-speed micro-turbines for distributed power generation systems.
Another related area of interest is the development of innovative rotor supports for high-speed kinetic energy storage devices (flywheels).
