About Me

I am currently a research assistant at the Lab for Atomic and Photonic Technologies at Northwestern University, where I am finalizing my PhD in Electrical Engineering with a focus on photonics with an expected graduation date of June 2024. My primary research is in applications of analog and digital holography, with a particular focus on optical signal processing and data acquisition. I also research the development of photonic integrated circuits in AlGaAs/GaAs and LiNbO3 for use in fast and slow light gyroscopes using Rb atoms.
I'm passionate about developing new and interesting ways to use the complex nature of light in everything from fundamental science to entertainment. Light is an incredible tool that we are only just beginning to fully dominate; it allows us to observe from the very structure of the universe to its most minute particles, while simultaneously connecting us to virtual worlds limited only by our imagination. I strive to design technologies that truly take advantage of this fundamental force in order to improve the human experience.
