The Cosmic Dawn Survey
The Cosmic Dawn Survey is a 50 square degree multi-wavelength survey of the Euclid Deep and Calibration fields. The scientific aim is to understand the co-evolution of galaxies, black holes, and the dark matter haloes that host them from Re-Ionization (z~12, about 500 million years after the big-bang) to the present (z~0). The current dataset comprises ultra-deep griz imaging as part of the H20 Survey and IRAC infrared imaging from the Spitzer Legacy Survey, and will eventually include near-infrared imaging from the Euclid Space Mission from 2022. I am a co-lead of the photometric extraction, redshift computation, and physical parameters team, using The Farmer to produce bleeding-edge measurements of galaxy properties.

Postdoctoral Research Associate
My research interests lie almost exclusively within the realm of extragalactic astrophysics and cosmology. I use state-of-the-art optical and infrared observatories and surveys to study the lives of galaxies, and how their properties change over cosmic time. This includes detailed case studies of individual galaxies, as well as statistical analyses of large survey catalogs.
