Advances in nano-fabrication over the past few decades have enabled the study of material structures with features at the scale or smaller than the electromagnetic wavelength. These engineered materials (photonic crystals, plasmonic nanoresonators, and metamaterials) can lead to a wide range of unusual optical behaviors (photonic bandgaps, ballistic transport, ultra-slow propagation, and negative refraction) which allow unprecedented control and tunability over the properties of light.

Our group's focus is on applying and developing theoretical and computational techniques to explore the ways in which complex nanostructures can lead to new optical phenomena and devices. Current and past research interests include:

  • Fluctuation phenomena (Casimir and van der Waals forces, thermal radiation, spontaneous emission)
  • Nonlinear optics
  • Fundamental limits on optical phenomena
  • Large-scale photonic optimization (inverse design)
  • Topological photonics
