About Me

I have been an astrophysicist for over 35  years. My core research interest is the empirical investigation of giant black holes that are found in the centres of distant galaxies.

My science questions are focused on the  phenomenology of accreting supermassive black holes, and I gather and use  data from telescopes that operate at radio, infrared, optical, ultraviolet, X-ray and gamma-ray frequencies.
