I'm Zack LiADS, a cosmologist. I think about the cosmic microwave background, the redshifted 21cm line, the large-scale structure of the Universe, and the nature of dark matter.

I am a postdoctoral fellow at UC Berkeley (BCCP) and a long-term visitor at CITA.

I spent two formative years as a postdoctoral fellow at the Canadian Institute for Theoretical Astrophysics (2021-2023, CITA). From 2016-2021, I was a PhD student in astrophysics at Princeton, working with Jo Dunkley on data analysis for millimeter-wave surveys like ACT, SO, and CMB-S4. From 2012-2016, I studied math and physics at Swarthmore College.

I like new data, fast code, and crazy ideas.

What I really wanted was every kind of life, and the writer’s life seemed the most inclusive.
