Research

My research program focuses on the spectroscopy of novel electronic and magnetic materials. We have four major initiatives. These include:

  • The interplay between charge, structure, and magnetism in complex materials as investigated with different physical stimuli
  • Chemical and photochemical tuning effects in malends
  • Finite length scale effects on charge and bonding in nanomaterials
  • Energetic materials: optical properties of polar oxides, electrode materials, battery compounds

These themes are unified by the use of optical spectroscopy as a tool to understand local structure and functionality.
