Ceramic Tech Chat

Undergraduate research experiences have many well-known benefits for those just starting on their potential career path. Mario Affatigato, the Fran Allison and Francis Halpin Professor of Physics at Coe College, shares how his initial experiences with glass research as a student at Coe came full circle when he returned to Coe as a professor, describes the fundamental and applied glass science that his research group conducts, and discusses his plans and goals as president of ACerS this year.

About the guest
Mario Affatigato is the Fran Allison and Francis Halpin Professor of Physics at Coe College in Cedar Rapids, Iowa. His group studies various glass-related questions from both a fundamental and applied perspective, including electrical conductivity of vanadate glasses and laser-based manufacturing. He is serving as this year’s president of The American Ceramic Society, and he is also editor-in-chief of the International Journal of Applied Glass Science. 
About ACerS
Founded in 1898, The American Ceramic Society is the leading professional membership organization for scientists, engineers, researchers, manufacturers, plant personnel, educators, and students working with ceramics and related materials.

Reducing carbon emissions in the cement and concrete industry is a complex, multifaceted challenge. Juan Pablo Gevaudan, assistant professor of architectural engineering at The Pennsylvania State University, talks about how his childhood desire to protect the environment led to his eventual work in cement, describes some of the research taking place in the cement industry to reduce carbon emissions, and shares how his identity as a Latino and Hispanic scientist plays a role in his approach to learning and teaching.

Glass is generally considered inert, but recent decades have seen increasing interest in glasses that react more readily with their environment. Courtney Calahoo, research and development team lead at Genics, shares her journey to working on dissolvable glasses, describes some of her current projects, and provides examples of how Indigenous knowledge can benefit modern scientific research.

About the guest
Courtney Calahoo is research and development team lead at Genics Inc., a chemical manufacturer in Alberta, Canada. She became interested in dissolvable glasses while working in Lothar Wondraczek’s group at the Otto Schott Institute of Materials Research, and she now develops dissolvable glass rods for wood preservation at Genics. During the International Year of Glass celebrations at the United Nations in 2022, Courtney talked about her experiences as an Indigenous woman glass scientist and the overlap between Indigenous knowledge and glass science.
