NON-PREFERRED (astronomy pivot, kept for review). Burdge discovers and characterizes compact binary systems (white dwarfs, neutron stars, black holes) using time-domain, multi-messenger methods, and develops ultrafast sub-electron-noise optical camera instrumentation (Lightspeed) for ground-based telescopes; this is a good fit for the 'sufficiently complicated sensor enabling temporal resolution' astro-pivot category rather than core quantum sensing.
