- PhD / DPhil (University of Manchester)
Summary
I am an astrophysicist at the E.A. Milne Centre for Astrophysics and a lecturer in the Centre of Excellence for Data Science, Artificial Intelligence and Modelling (DAIM). I work on radio astronomy of pulsars, using some of the most sensitive telescopes in the world. My main areas of research are pulsar timing, the interstellar medium, and single pulse emission from pulsars.
I studied Physics at the University of Hull and was awarded a Ph.D. in Astronomy & Astrophysics by The University of Manchester. I have held research positions at the Max Planck Institute for Radio Astronomy and the Canadian Institute for Theoretical Astrophysics.
I am a member of several international collaborations including:
Canadian Hydrogen Intensity Mapping Experiment (CHIME)
North American NanoHertz Observatory for Gravitational Waves (NANOGrav)
Large European Array for Pulsars (LEAP)
European Pulsar Timing Array (EPTA)
International Pulsar Timing Array (IPTA)
The NenuFAR array
