Research:

My research focuses on the confinement of electromagnetic energy and charged particles in the nano- to atomic-scale dimensions and the interactions between such confined systems. This involves the sub-diffractional confinement of light using 'polaritons' within the optical spectral domain (primarily the infrared), the design of nanoscale optical components, and identifying and characterizing novel optical, electro-optical and electronic materials.
