My published work spans active photonics, sensing systems, and ultrafast optics, from
semiconductor ring lasers and frequency-comb dynamics to thin-film photonic coatings
and infrared sensing platforms.
I've been lucky enough to publish with a great group of collaborators, across
a variety of journals such as Nature, Nature Nanotechnology, and Physical Review Letters.
