William (Bill) Reach is an expert on studies of infrared emission from Solar System, including the zodiacal light, comets, and the Moon. He is also an astrophysicist with studies of the diffuse interstellar medium, supernova remnants, and cosmic backgrounds. He wanted to be an astronomer since he was 5 years old (no joke) and followed a formative path from interning at Fernbank Planetarium and Georgia State University.
