Background

Dr. Varenberg began at Georgia Tech in Fall 2014. Prior to this appointment, he was an Assistant Professor in the Dept. of Mechanical Engineering at the Technion – Israel Institute of Technology. Dr. Varenberg has also previously held a Researcher position in the Evolutionary Biomaterials Group at the Max Planck Institute for Metals Research.

Research

Dr. Varenberg is engaged with two major research domains:

• Exploration of the tribological solutions evolved in the biological world. This multinational interdisciplinary research, which involves joint work with biologists, seeks to understand and mimic the behavior of interacting surfaces in the world of animals and plants, while uncovering the biological side of adhesion, friction, lubrication and wear. Research thus far has led to development of two new types of bio-inspired surfaces, which have a strong potential to be imbedded in a variety of products in daily and industrial use.

• Development of green aspects of classical tribology. This multidisciplinary research sets problems at the interface between physics, chemistry, material science and mechanics, and aims at increasing efficiency, integrity and cleanliness of modern surface technologies. Research thus far has resulted in laying a cornerstone of a new family of mechano-chemical surface treatments, which are expected to bring eco-innovation to friction surfaces in transportation, industrial and power-generation sectors.
