The Bragg Lab has several research interests focusing on ultrafast processes that underlie the behaviors of a range of light-responsive materials. An overarching goal of our work is to understand how structure or material architecture at the intra-, inter-, and supramolecular levels influence the properties and dynamics of transient excited and charge-separated states generated via molecular or material photoexcitation and thereby determine the nature, timescales, and efficiencies of processes initiated with light – such as bond formation, energy transfer, and charge separation.  We are also excited about new and interesting ways to study these systems with light. Have a look at our website to learn more about us and our work!
