Research Statement

Though crystalline materials are often characterized by periodic order, of particular interest to my research is how correlated disorder and competing local forces give rise to unusual phenomena that are inaccessible to perfect crystals, yet are crucial for energy storage and other applications. We approach these scientific questions by coupling synthesis and property measurements with advanced total scattering and spectroscopic characterizations. Materials systems of particular interest to us include ion-intercalation and ion-conducting materials for battery applications, as well as quantum materials with non-trivial topological band structures.
