I am the Professor of Astrostatistics and Data Science at the University of Cambridge. I hold this interdisciplinary faculty position jointly at the Institute of Astronomy and at the Statistical Laboratory of the Department of Pure Mathematics and Mathematical Statistics. My astronomy office is located in the Kavli Institute for Cosmology. From 2023, I am Chair of the Astrostatistics Interest Group of the American Statistical Association.
My research interests lie at the intersections of astrophysics, cosmology, statistics, and machine learning, and include:
My research group is a partner in the Young Supernova Experiment time-domain survey using the Pan-STARRS telescopes.
We are also members of:
We are funded by a European Research Council Consolidator Grant.
