My group is interested in a wide variety of problems that can be solved (or at least addressed) through the enabling capabilities of advanced ceramic materials. In particular, our work tends to focus on materials that do something interesting under an applied electric field (e.g., dielectrics, piezoelectrics, ferroelectrics). We are especially interested in the dynamic response to electric field, from nanosecond processes (e.g., ferroelectric polarization reversal and domain wall dynamics) to long-term defect migration and associated degradation and reliability issues, particularly under challenging (e.g., high temperature, high electric field) operating conditions. Of course it is a rare case when a single stand-alone material is the solution to any engineering problem, so clever processing to enable fabrication and integration of these functional materials into useful devices and systems underlies all of our research.
