Biography

Dr. Ryan specializes in the study of the structure and properties of glass and ceramic materials, with a focus on surface-related techniques and effects. This approach has been utilized with materials produced by a variety of processing techniques, including bulk ceramic processing, traditional glass melting, non-oxide and other specialty glasses, and sol-gel routes. He is also involved in the design, synthesis and characterization of thin film materials for use in optoelectronic, infrared, tribological, and barrier applications.

Dr. Ryan is currently working on challenges establishing international consensus on long-term corrosion rates of nuclear waste forms. He is also involved in the development of novel alternative waste forms for the sequestration of problem radionuclides such as iodine, krypton, cesium, and strontium. He is an active member of the American Ceramic Society, currently serving as program chair for the annual meeting on the science of glasses and other optical materials.
