Junki Joe's, PhD, scholarly interest focuses on the contact mechanics of rough surfaces. He develops theoretical models to predict how the surface roughness affects mechanical contact properties.
He conducted postdoctoral research at the University of Utah, bridging the gap between tribology and metal additive manufacturing. His work has been featured by the Society of Tribologists and Lubrication Engineers. As a postdoctoral fellow at the National Renewable Energy Laboratory, he investigated electrical failures in photovoltaic modules due to wear.
Joe's teaching goal is to help engineering students become engineers, not simply experts at solving well-defined textbook problems.
