I am a postdoctoral scholar working in Mikael Rechtsman's group in the Department of Physics at Pennsylvania State University. Prior to starting at Penn State, I completed my doctorate in physics with Douglas Stone at Yale University, and spent two years working as a postdoc with Shanhui Fan at Stanford University.

I'm currently interested in the novel phenomena possible in topological and non-Hermitian photonic systems, such as Weyl exceptional rings, bound states in the continuum, and higher order topological insulators, and I explore through analytical, numerical, and experimental techniques. 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 recent projects, please head over to my research section.
