Research interests: miniature quantum sensors (atomic-clocks, optical magnetometers, E-field sensors), time and frequency, miniature frequency-combs (micro-combs), and the interplay between photonics and atomic-physics. We study interactions among diverse ‘flavors’ of photons and atoms in order to (a) develop novel types of miniature quantum-sensors, and (b) understand light-matter interactions of light and atoms occurring at minuscule dimensions.
