I work on a variety of problems in high-redshift astrophysics, other areas of astronomy, astrostatistics, and machine learning. My research is inspired by astrophysical phenomena whose explanation has been cast into doubt, either by new theoretical ideas or new observations. Prior to coming to Missouri, I was a founding member of the Cosmic Dawn Center, a Danish National Research Foundation Center of Excellence hosted by the Niels Bohr Institute and Danish Technical University. I also run an undergraduate research program every summer. I received an A.B. in Astrophysical Sciences from Princeton University, and S.M in Astronomy, S.M. in Computer Science, and Ph.D. in Astronomy from Harvard University. 

Teaching: I will be teaching ASTRON 1010 in Spring 2025 and a new applied machine learning course in Fall 2025.

We will be hosting the first University of Missouri Physics Contest on April 5, 2025.
