My research interests are primarily based upon exploring novel phenomena in solid state systems, in order to provide the physical foundation for future technologies. Areas of interest include physical systems capable of quantum information processing and quantum computation, nanoscale control over metal-insulator transition in polar/non-polar oxide heterostructures, the study of ferroelectric domain dynamics using optical probes, ferroelectrically nanostructured semiconductors, formation of Ge/Si quantum dots by "directed self-assembly", and development of novel optical and scanning probe techniques including near-field optical microscopy. I am the director of the Center for Oxide-Semiconductor Materials for Quantum Computation (COSMQC).
