I'm starting a theoretical and computational photonics group at the Center for Integrated Nanotechnologies and within Sandia National Laboratories' Nanostructure Physics Department in Albuquerque, NM.

Broadly speaking, my research interests lie in developing novel types of photonic structures that can exhibit new physics or enable new applications. Currently, I'm interested in exploring phenomena which are found at the intersection of topological and non-Hermitian physics, such as Weyl exceptional rings, bound states in the continuum, and the corner-localized states present in systems with higher-order topology. My research is about equally divided between analytical, numerical, and experimental work. In the past, I have also worked on more general theories of the quantum limited laser linewidth and designing highly multi-mode lasers for use as high-power incoherent light sources. For additional information about some of my current interests and recent projects, please head over to my research section.
