Research
I am a third year PhD student working on Bayesian inference and machine learning methods, and their applications in astrophysics and cosmology. Recently my research has involved nested sampling, Bayesian sparse reconstruction, neural networks and gravitational waves. I created the dynamic nested sampling algorithm, a generalisation of nested sampling can significantly improve efficiency, and am the author of the dyPolyChord, nestcheck and perfectns packages.
