Research Interests:
Tomas Grejtak a postdoctoral research associate in the Surface Engineering & Tribology Group, Materials Science and Technology Division. His research focuses on wear, friction, materials deformation and contact mechanics of various materials and systems ranging from ultra-low wear thin film coatings to hard biomaterials. Grejtak has an extensive expertise in materials characterization including wear and friction experiments, nanoindentation, and high resolution microscopy.
