Research Interests

The main thrust of our research activity is focused on Manipulation and Management of Light through Materials Engineering. By developing structural models of materials that exhibit extremely long duration persistent luminescence, we are designing materials for zero energy consumption lighting. Our model systems are rare-earth co-doped alkali earth aluminates, which we analyze by applying advanced TEM, Raman, and other characterization methods.

Based on the insight that we have gained into the formation of boroaluminate crystal structures, we apply our models of thermodynamic and kinetic control to tune crystal structure in functional ceramics for energy storage and more sustainable cement processing. This work further motivates us to develop hubs of circularity for more sustainable, carbon-negative, high-volume materials processing.

By harnessing physical phenomena arising from cooperative behavior and localization, we are developing plasmonic materials for sensor and antenna applications, with a recent emphasis on developing new inorganic materials exhibiting plasmonic behavior.

To address the interdisciplinary nature of our work, team members are active in many collaborative national and international projects (see project details below and in publications).
