Andrei Nomerotski joined the U.S. Department of Energy’s Brookhaven National Laboratory to build a three-gigapixel camera for the Large Synoptic Survey Telescope (LSST), a massive instrument that will be installed in the mountains of Chile to capture the deepest and widest snapshots of the cosmos to date. The LSST is Nomerotski’s main focus, yet he manages to find time to run a side project at Brookhaven: developing an ultrafast camera, called TimepixCam, that can detect either single photons or ions for astrophysics experiments and even more down-to-earth studies in fields from biology to quantum computing.
