Research

I am the University Lecturer (≈ assistant professor) on Astrostatistics at the University of Cambridge. I hold this interdisciplinary faculty position jointly at the Institute of Astronomy and the Statistical Laboratory in the Department of Pure Mathematics and Mathematical Statistics.  My astronomy office is located in the Kavli Institute for Cosmology.  My research interests lie at the intersections of astrophysics, cosmology, statistics, and machine learning, and include:

• Supernova cosmology
• Astrostatistics & astroinformatics
• Time-domain and transient astronomy
• Bayesian modeling and inference
• Statistical computation
