Born in Newcastle-upon-Tyne, I was educated at Ravenswood Primary School, The Edinburgh Academy, Imperial College, University of London (BSc Physics), and St Andrews University (PhD -- Studies in Stellar Evolution). Before moving to Armagh, I worked at the Royal Observatory Edinburgh on ultraviolet astronomy and planetary atmospheres, at the University of St Andrews as an SERC-funded research assistant on helium stars, the Christian-Albrechts University at Kiel as a Royal Society European Research Fellow on pulsating helium stars, and again at the University of St Andrews as a senior research assistant (CCP7) on the analysis of astronomical spectra. In 1996 I took up a position as senior research astronomer at the Armagh Observatory, since when I have supervised over 15 PhD students, and taught Stellar Structure and Evolution to at least 12 cohorts of Trinity College Dublin physics and astronomy students. From 2007 to 2012 I led the construction of the Polar Bear Survey Telescope and the Armagh Robotic Telescope. I have served as secretary and chairman of the Astronomical Science Group of Ireland, and as President of Commission G4 (Pulsating Stars) of the International Astronomical Union. In 2019 I took up a visiting by-fellowship at Churchill College, Cambridge. I can frequently be found on a sailing boat.
