About Me

Hello! I am a cosmologist who studies the large-scale structure of the Universe. I am a Chamberlain Postdoctoral Fellow at Lawrence Berkeley National Laboratory, with affiliation at the Berkeley Center for Cosmological Physics. My research focuses on developing novel and robust statistical methods to test fundamental physics using large-scale galaxy surveys, with an emphasis on controlling the observational systematics that increasingly limit what these surveys can teach us.

Research

The next generation of cosmological surveys is mapping the positions and properties of billions of galaxies across cosmic time, offering an unprecedented window onto the growth of cosmic structure, the nature of dark energy, and the validity of general relativity on the largest scales. Leveraging the full statistical power of these surveys requires advanced methods to model the full complexity of our observations and to identify and correct for systematic errors which increasingly dominate the error budget of cosmological analyses with modern surveys.

Much of my work develops and applies techniques to extract reliable cosmological information from the large-scale structure of the Universe while carefully controlling for observational biases. A key component is identifying and controlling observational effects that can masquerade as cosmological signals, so that our measurements can be used to produce accurate constraints on cosmological parameters.

I am an active member of the Dark Energy Survey (DES) collaboration, where I co-lead the Large Scale Structure Systematics analysis team, as well the Dark Energy Spectroscopic Instrument (DESI) collaboration. Currently, I spend much of my time focused on the interface of spectroscopic and photometric surveys, where I work to develop novel observational and analysis techniques that compound the value of our data and improve the information we can extract from weak lensing surveys. I am also broadly interested in the role of science in society, and responsibilities and opportunities we have living through climate breakdown. As a core member of the DESI Sustainability Committee, I helped assess the climate impacts of DESI as a large international science collaboration and chart potential pathways toward a more responsible and sustainable science aligned with the Paris Climate Agreement and UN Sustainable Development Goals.

Background

Before joining Berkeley Lab, I was a graduate student and research assistant at the University of Michigan, where I completed my doctoral studies in physics under the supervision of Prof. Dragan Huterer.
