I am the Professor of Astrostatistics and Data Science at the University of Cambridge. I hold this interdisciplinary faculty position jointly at the Statistical Laboratory of the Department of Pure Mathematics and Mathematical Statistics, and at the Institute of Astronomy. As of 2024, I am the Past Chair of the Astrostatistics Interest Group of the American Statistical Association, a member of the Council of the International Astrostatistics Association, and Turing Fellow Alumnus of The Alan Turing Institute. I am a founder and co-organiser of the Cambridge Astro Data Science Discussion Group. My research interests lie at the intersections of astrophysics, cosmology, statistics, and machine learning, and include:
- Astrostatistics, astronomical machine learning, astroinformatics
- Statistical applications in time-domain astronomy and cosmology
- Bayesian modelling and inference
- Statistical computation
