Enrique Paillas

I am an astronomer and cosmologist, currently working as a Postdoctoral Associate at the Department of Astronomy & Steward Observatory of the University of Arizona. My research focuses on observational cosmology, combining theory and observations to learn about the nature of dark energy, the growth of cosmic structure, and the physics of the early Universe. I will be starting as an Assistant Professor at Universidad Diego Portales in spring 2026, where I will lead a new cosmology group (click here to learn about research opportunities).

I grew up in Santiago de Chile, where I obtained my PhD in astrophysics from Pontificia Universidad Católica de Chile, working under the supervision of Nelson Padilla. Before moving to Arizona, I worked as a postdoctoral fellow at the Waterloo Centre for Astrophysics, in Ontario, Canada, where I collaborated with Will Percival on various topics of large-scale structure science.

I am an active member of the Dark Energy Spectroscopic Instrument Collaboration, where I co-chair the Galaxy & Quasar Clustering working group. I also participate in the LSST Dark Energy Science Collaboration, where I am interested in exploring weak lensing and supernovae science.
