An experimental <optical physicist> who coauthored measurements of the spatial coherence of three bright stars. Separate telescopes recorded intensity fluctuations whose correlations depend on their separation, applying <stellar intensity interferometry> to angular measurements. The approach links a laboratory quantum-optics correlation to a stellar observation.<Spatial intensity interferometry on three bright stars by William Guerin and others>[Abstract and two-telescope correlation measurements]{ref}
