Research Interests

Dark Matter and Cosmology

I'm interested in the particle nature of dark matter. I think there's a lot we can learn about dark matter by studying cosmology, especially given the flood of new data we are receiving from incredibly precise experiments.

At the moment, most of my work pertains to the early universe. I think about the formation of the first light element nuclei (Big Bang Nucleosynthesis, or BBN), the formation of the first neutral atoms and the radiation that escapes during that process (recombination and the Cosmic Microwave Background, or the CMB), and how signals from each of these epochs can tell us more about dark matter and other new physics.

Computational Work

Most of my work is with computers, and there has been an explosion of new computational methods that makes it a very exciting time to be digging around in code! I'm particularly excited about using JAX to modernize our suite of computational tools in cosmology, in broader physics, or even in science in general.

I wrote a BBN code called LINX, which is written in JAX and is publicly available on my GitHub.

You can check out my INSPIRE record, my ORCiD profile, or my arXiv listings to see my most recent papers. In general these (especially arXiv) will be more up-to-date than my CV.

You can find a copy of my CV here, which was last updated November 2024.

I'm wary of spam! For physicists: if you'd like to get in touch with me, check out any of my recent papers on the arXiv for my email address.
