I am a Pappalardo Fellow at the Massachusetts Institute of Technology in the Department of Physics and the Kavli Institute for Astrophysics and Space Research . I received my PhD in astrophysics at the University of California, Berkeley in 2020. I am a data-focused cosmologist, working at the interface of radio observations, data analysis, and theoretical inference for 21 cm cosmology. I am an expert in developing novel tools for identifying weak signals in large, noisy, and contaminated datasets, and for m
The Hydrogen Epoch of Reionization Array (HERA) is a new radio interferometer that aims to detect the 21 cm signal from cosmic hydrogen at the Epoch of Reionization and Cosmic Dawn. I led the first analysis of HERA Phase I observations, which set new upper limits on the power spectrum at z=7.9 and z=10.4 ( HERA Collaboration 2022a ). In particular, I led the development of HERA's precision systematic modeling algorithms (see below), which were critical in enablign HERA's improved measurements: our z=7.9 lim
