Research interest

Polymer tribology deals with mechanisms and regularities of friction and wear of polymers and polymer-based composites. It studies a variety of processes running in the contact at friction of such materials.

Biotribology , friction, wear and lubrication in biological environments, in the body's joints, such as hip and knee & Bio-compatible materials especially orthopedic materials development: to develop new implant materials with improvement of certain properties for use in load-bearing joints
