Introduction: Dr George K. Nikas is a professional Mechanical Engineer licensed since 1995. He graduated from the National Technical University of Athens, Hellas, in 1994, and received a Ph.D. and D.I.C. degree in Tribology and Contact Mechanics from the Mechanical Engineering Department of Imperial College London in 1999. He worked for nearly 10 years as Research Assistant and Research Associate in the Mechanical Engineering Department of Imperial College London. He has served as Associate Editor of the Journal of Tribology (American Society of Mechanical Engineers) and Member of the Editorial Board of 5 other engineering journals.

Running tasks and research areas: scientific research and technical publishing in Tribology and Contact Mechanics. Mathematical analysis and computational modelling of tribological problems; effects of lubricant contamination particles; elastohydrodynamics and mechanics of hydraulic seals, toroidal Infinitely Variable Transmissions, spur gears and rolling bearings; hydrodynamics of thrust and journal bearings, including gas bearings; mechanical and thermal stress analysis; contact mechanics involving linear and nonlinear (rubber) elasticity, thermoelasticity, poroelasticity; fatigue life calculations; Finite Element Analysis; surface coatings.
