Alex is an astrophysics PhD student at the University of Birmingham. He is researching hierarchically modelling many stars with machine learning methods to improve inference of their ages, masses, and chemical compositions. More accurate stellar properties help decode the evolutionary history of the Milky Way and exoplanet systems. He uses photometric time series data from NASA missions, such as Kepler and TESS, to study the oscillations of stars, unlocking information about their interiors through asteroseismology.
