John Mauro is an expert in fundamental and applied glass science, statistical mechanics, computational and condensed matter physics, thermodynamics, and the topology of disordered networks. He is a pioneer in the use of physics-based modeling for the design of new glassy materials and is the inventor of new models for supercooled liquid and glass viscosity, glass structure and topology, relaxation behavior, and thermal and mechanical properties. Prior to coming to Penn State, Mauro worked at Corning where he was the inventor or co-inventor of several new glass compositions, including Corning Gorilla® Glass products.

Building on more than 18 years of industrial research experience, Mauro uses a combination of theoretical and experimental approaches to address fundamental problems in glass science and engineering. Two of his key research areas are glass transition and predictive design of new glassy materials by “decoding the glass genome.” Other research areas include: high-strength glasses, with particular emphasis on chemically strengthened glasses; nucleation/crystallization in glasses and glass-ceramics; and glass melting and processing.

“'The polymer is better at flexibility; it’s easier to bend at the same thickness,' says John Mauro, a professor of materials science and engineering at Penn State University who had previously spent 18 years at Corning."

"Fiberglass doesn’t draw much attention, yet it’s a common material important to modern life. 'People may think glass fibers are low tech,' Penn State’s Mauro says, but tuning their composition to customize properties is 'cutting-edge chemistry.'"

“'You get to a point where there’s only so much you can do within a given family of glass compositions, and that’s when it becomes necessary to go to a completely new family of glasses that can offer some enhanced property that was not previously available,' says John Mauro, a professor of materials science and engineering at Penn State."

“'It combines features of solids and liquids,' paper author John Mauro, Penn State scientist and inventor of Gorilla Glass for Corning Incorporated told Gizmodo. 'We proposed a new definition of glass to accurately capture both features.'
