My professor mentioned it in the observational astronomy class I took in college. For anyone wondering, zodiacal dust is the stuff left over from the protoplanetary disc that didn’t become a planet. Any observations made along the plane of the solar system is looking through that dust and astronomers need to account for it in various ways.
May’s actual thesis was called “A Survey of Radial Velocities in the Zodiacal Dust Cloud.”
