An experimental <optical physicist> who coauthored stellar <stellar intensity interferometry> measurements. Correlating fluctuations detected at separated telescopes probes the spatial coherence of starlight. The method extracts angular information from photon statistics rather than requiring the optical electric fields from the telescopes to remain phase locked.<Spatial intensity interferometry on three bright stars by William Guerin and others>[Abstract and intensity-correlation measurement]{ref}
