Polycarpou, Andreas Professor and Head
Positions
- Faculty Affiliate, Energy Institute, Texas A&M Engineering Experiment Station (TEES)
My research interests include tribology, nanotechnology, microtribology related to miniature systems, magnetic storage, surface characterization, friction/vibration interaction, system dynamics and modeling, and experimental design and instrumentation. Specifically, I study micro/nanotribology of magnetic head disk interfaces and microelectromechanical systems. Recent emphasis has been on the tribology of devices for reduced energy and improved environmental-related impact, such as the use of carbon dioxide as a natural refrigerant and the use of surface treatments towards oil-lees machine operation.
