• Nishan and Steve, for an article on light-matter interactions on the very small scale (check those cool group teeshirts!)

Selected Research Interests: nanophotonics, semiconductor optics, quantum optics, light-matter interactions, photonic crystals, cavity-QED, quantum dots, computational electromagnetics, optomechanics, disorder-induced scattering, metamaterials, quantum plasmonics, topological photonics, computational physics.


We are actively seeking outstanding graduate students – MSc, PhD, and Accelerated Masters, and occasionally have positions for post-docs. See Opportunities for more details and contact me if interested. We especially welcome applications from strong female candidates and underrepresented groups in physics.

Queen’s accelerated master’s students: We welcome applications from strong accelerated master students to join our group, starting May 1, 2021 (3rd year students). Please contact me if interested. You can learn more about this excellent program here, with some comments from some of my previous accelerated master’s students here. You will be offered an exciting selection of world-leading research topics related to quantum nanophotonics and light-matter interactions. 

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  optics, condensed matter physics, 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. We have several labs including a state of the art computational modelling lab and a dedicated collaboration lab, funded through a CFI Innovation Grant, as part of the Queen’s Nanophotonics Research Centre.

Research projects encompass a broad spectrum of fundamentals and applications of light-matter interactions, and includes 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, 2d materials, optomechanics 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. We are also interested in new methodologies in quantum optics including methods to describe cohernet feedback, electron-phonon interactions and the quantization of quasinormal modes. To learn more about our exciting research activities, please see Publications and Research sections above and look over some of our recent publications.
