I am an Astronomy PhD student at the University of Massachusetts, Amherst advised by Kate Whitaker. I graduated with a BS in Physics from the University of Connecticut in 2019. In my research, I focus on the formation and evolution of galaxies via large photometric and spectroscopic surveys and galaxy morphology.
In the past, I have studied the relationship between galaxy structure, environment, and star formation through the creation of the COSMOS-DASH morphological catalog. I have also investigated the different formation histories of the inner and outer parts of typical star-forming galaxies near cosmic noon using the Prospector code. Recently, I have been working with photometry and source detection in HST (3D-DASH) and JWST (PRIMER and UNCOVER) surveys, assisting in the creation and development of the aperpy aperture photometry code and photometric catalogs for each of these programs. Using the rich JWST data from PRIMER and UNCOVER, I am currently investigating the formation low-mass quiescent galaxies via morphological analyses in NIRCam F150W and F444W.
Outside of research, I am an active member in science outreach with UMass Astronomy, where we hope to make science accessible to the larger community and encourage interest in astronomy.

Star formation histories of the inner and outer components of main sequence galaxies using resolved SED fitting
Using the JWST UNCOVER and PRIMER Treasury surveys, we measure the sizes of 332 7<logM<11 quiescent galaxies at cosmic noon (1<z<3). We find that there exist two distinct populations of quiescent galaxies at this epoch: a young, low-mass, disky population and an older, massive, spheroidal population, further highlighting the different mechanisms involved in galaxy evolution at low masses.
We present a study of spatially-resolved star formation histories for 60 z~2.3 main-sequence, star-forming galaxies. The results suggest that selecting star-forming galaxies at cosmic noon frequently includes systems in an “evolved” evolutionary phase where the centers have recently started a burst of star formation activity that will likely initiate inside-out quenching in the next several hundred million years.
