Thanks for visiting our website. We carry out theoretical and computational investigations of the light-matter processes in photonic nanostructures, and explore the consequences of these for next-generation nano and quantum technologies. Our research blends a fascinating mix of condensed matter physics, optics, quantum mechanics, nano physics, and computational physics. We collaborate with leading laboratories throughout the world, with a focus on applicable theoretical physics that is interesting from a fundamental physics perspective and has potential applications, especially in quantum technologies. We particularly enjoy collaborating with experimental groups. Our work is funded by various funding bodies, including NSERC, CIFAR, MRI Ontario, CFI, and Queen’s University.

My students, collaborators and I are interested in optics and condensed matter physics on the nanoscale. Nanoscale materials contain spatial features that are on the nm (nanometer) length scale, which is about 1-50,000th the width of a human hair or the length of only 10H atoms! This incredibly small size gives rise to a range of exciting new optical regimes where it is now possible to confine and manipulate individual photons and excitons (or electron-hole pairs) simultaneously. Research projects encompass a broad spectrum of fundamentals and applications, and include the study of classical optics, quantum optics and nonlinear optics in a variety of photonic nanostructures such as photonic crystals, single quantum dots, chiral waveguides, and metal nanoparticles. We tend to tackle both important and challenging problems, including some of the realities that are usually ignored, such as the effects of fabrication imperfections (structural disorder), material loss, and decoherence on light scattering.
