I am the University Assistant Professor of Astrostatistics 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. I am also a Turing Fellow at the The Alan Turing Institute. From 2022, I am Chair-Elect 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:

  • Supernova cosmology
  • Astrostatistics, astronomical machine learning, astroinformatics
  • Time-domain and transient astronomy
  • Bayesian modeling and inference
  • Statistical computation

My research group is a partner in the Young Supernova Experiment time-domain survey using the Pan-STARRS telescopes.
We are also members of:
