Dr Michael Goad

Associate Professor

Profile

Graduated 1988 BSc 1st class honours (University of Newcastle Upon Tyne). 1989-1994 PhD University College London, 1995 HSO Rutherford Appleton Laboratory, 1995-1998 Postdoctoral Research Assistant Space Telescope Science Institute, Baltimore, April-Nov 1998 Postdoctoral Research Assistant, University of St. Andrews. 1998-2001 PPARC postdoctoral fellow University of Leicester, 2001-2004 Temporary Lecturer University of Southampton, 2004-2006 Swift Data Centre Scientist University of Leicester, 2006-present Lecturer University of Leicester.
 

Research

Currently focused on two research themes, Active Galaxies and Exoplanets. Research on Active Galaxies is focused on understanding the immediate environment near the central blackhole, the accretion disc and the high velocity, highly ionised gas (BLR). In particular we use continuum and emission-line variability studies to measure (i) the disc temperature profile, thereby testing the standard model, and (ii) to map the  BLR dynamics.
Exoplanet research focuses on new discoveries with NGTS (the Next Generation Transit Survey) and serendipitous science with a focus on low mass binaries.
