Guy R. Davies is an Associate Professor in Astrophysics. He uses the sounds of the Sun and stars in an attempt to understand the world around us, with a particular focus on the development and application of novel, advanced data-analysis techniques (including applications of machine learning and Bayesian inference).  He is an enthusiastic teacher and communicator on all aspects of astrophysics and is regularly involved in organized public outreach events.

Guy is an active member of the Birmingham Solar Oscillations Network (BiSON), the Kepler (NASA) Asteroseismic Science Consortium, and the COROT (CNES) team.

He is an enthusiastic teacher and communicator on all aspects of astrophysics and is regularly involved in organized public outreach events.

Qualifications

  • PhD in Astrophysics, University of Birmingham, 2011
  • MSci in Physics and Astrophysics, University of Birmingham, 2007

Biography

Guy R. Davies qualified with a first class MSci (Hons) in Physics and Astrophysics from the University of Birmingham in 2007. He continued his studies at Birmingham undertaking a PhD with the High Resolution Optical Spectroscopy group studying the instrumentation and data analysis of the Birmingham Solar Oscillations Network. Following the completion of his PhD in 2011, Guy moved to the Commissariat à l'énergie atomique in Saclay, France to work with the Global Oscillations at Low Frequency instrument on the SoHO spacecraft.

Guy’s research interests are focused around helio and asteroseismology. Ranging from radial-velocity instrumentation through to the modeling of oscillation power spectra and applying the fruits of extended observation to describe the structure and dynamics of the Sun and the stars. He is particularly interested in the rotation of the Sun and stars and its connection to the well known Solar activity cycle.
