Ed DawEd Daw is Professor of Particle Astrophysics at the University of Sheffield. He has worked as an experimental physicist since 1998, on searches for dark matter and gravitational waves.

He also enjoys trying to explain hard things in simple terms, a very good habit for a professor. Read More Read Less
