Dr. Samuel George
Radio Astronomer & Trainee Teacher @ the University of Birmingham
- I am an honorary research fellow in the Astrophysics & Space Research Group at the University of Birmingham. I was previously a postdoctoral fellow in the Astrophysics Group at the Cavendish Laboratory, University of Cambridge and before that at the University of Calgary. My main research interests are: Wide-field radio astronomical imaging; polarization imaging, calibration and statistics; magnetic fields in the Universe: galactic, planets, low mass stars; extrasolar planets (detection and atmospheric studies); planetary and stellar magnetospheres; brown dwarfs, low frequency radio observations; electron cyclotron maser emission. On these pages you will also find my current CV, and my full publication history.

Magnetic Fields
- Studies of the Milky Way and other nearby spiral galaxies all show well organised, large-scale magnetic fields. I'm involved in a bunch of projects exploring magnetism in the Universe.

Low Frequency Radio
- Low frequency observations are challenging. Radio Frequency Interference causes huge issues. Widefield imaging techniques are required to accurately image the data.

Planets & Stars
- Extrasolar planets are believed to produce strong bursts of radio emission and is related to processes in ultra-cool stars. I also work on occasion on optical photometric observations.

Survey Astronomy
- The statistical analysis of radio source counts can be used to investigate the evolution of galaxies. Fast and accurate algorithms are required for the SKA pipeline.

Imaging & Calibration
- I work on calibration of multi-beam single dishes for full polarization and imaging issues over wide bandwidths for ALFA on Arecibo, the GMRT and the Square Kilometre Array.

Posters & Talks
- I have given many talks and posters on my work. These include research conference and public outreach audiences. When possible I try to include these online.
