Y research interests are to develop new electrochemical materials for energy storage, brain-inspired computing, and information processing. Many ionic materials can host a high density of point defects, which are mobile and act as dopants. Whereas silicon and other semiconductors usually have dopant concentrations below 1018 cm-3, ionic materials can have dopants concentrations above 1022 cm-3, on the order of one formula unit. When integrated into an electrochemical redox system, such point defect dopants can be inserted and removed dynamically upon the application of electrochemical current and voltage
