Dr. Varenberg’s research area is Tribology – the science and technology of interacting surfaces that allow for game-changing advancements ranging from making fire and inventing wheel in the past, to enabling human joint replacement in the present. Dr. Varenberg’s main focus is on bionic tribology and green tribology, but, to enhance the public’s interest in tribology science, he also seeks to uncover tribology from daily life, with examples of works on safety razors and table tennis paddles.
