Research

Supervised by Professor Debora Sijacki and Dr. Alexandra Amon, I am studying baryonic feedback using both cosmological structure formation simulations (the FABLE hydro-simulations) and observational data.  Improved understanding of this effect will allow future weak lensing surveys to make more powerful cosmological constraints, ultimately advancing our knowledge of the Universe's contents and expansion history.  I am also interested in testing whether more extreme models of AGN feedback are able to reconcile the current tension in cosmology between measurements of S8 by cosmic shear surveys and those by the Planck cosmic microwave background data. 

I am a member of the Dark Energy Survey (DES).  I will be performing a combined analysis of DES weak lensing and ACT kSZ data to constrain baryonic feedback from an observational standpoint.

I have previously been a member of the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey, where I also used both observational survey validation data and simulation-based mock catalogues to study the systematics affecting their future baryonic acoustic oscillation measurements.
