The COSMOS survey is one the longest-running galaxy surveys. Over two decades, we have collected observations of x-ray, optical, infrared, and radio light to obtain galaxy distances and understand their evolution over 13.7 billion years of cosmic history. I lead the 2020 edition of the master galaxy catalog, using bleeding-edge galaxy model-fitting techniques from The Farmer to measure galaxy properties.

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.
