Research

Throughout my PhD, I carried out my own near-infrared (NIR) supernova survey, called DEHVILS, which is perhaps the largest uniform sample of NIR SN light curves with good coverage. I have since gotten involved in preparing for NASA's next flagship mission, the Roman Space Telescope, which will also observe in the NIR.  

As a part of the Pantheon+ group, I was the first to correct for peculiar velocities in a SN cosmology analysis of this magnitude. And as the sample of SNe Ia grows substantially with surveys such as ATLAS, ZTF, and LSST, I am looking to account for motions inside groups for thousands of SN host galaxies.

Dust impacts all cosmological analyses, and recent results (i.e., DESI) have shown that treatments of systematics such as intergalactic dust can have large impacts on uncertainties on cosmological parameter measurements. I am currently working on constraining this systematic with DES data as well as LSST and Roman simulations.
