“I study proximity effects in complex oxides at the nano-scale. Oxides exhibit highly unique properties including collective phenomena such as magnetism, ferroelectricity, superconductivity, metal-insulator transitions, enhanced photoconductivity and electron transfer. Oxides also play a key role in both energy and information technologies. Examples include batteries, solar cells, catalysis, and miscellaneous electronic and magnetic devices.


My interest lies in the electronic, magnetic, optical and structural properties of materials and devices. I am interested in studying how systems change on mesoscopic or nano-length scales. In addition, proximity effects and external stimuli are tools that allow us to tailor the properties of these systems.”
