### Ph.D. Candidate, Yale Astrophysics

Investigating Galaxy Evolution & AGN
using custom-developed Machine Learning tools

## Hi There!

I am a Ph.D. candidate at Yale University. I use the latest advances in machine learning combined with large surveys to study the formation & evolution of galaxies, and investigate the specific role played by Active Galactic Nuclei in this process.

Most recently, I have been developing Bayesian machine learning frameworks to extract morphological parameters (e.g., radius, bulge-to-total light ratio) of galaxies & AGN. I have focused on enabling these frameworks to predict uncertainties which are well callibrated and accurate. I have used these to produce brand-new morphological catalogs for $\sim 8$ Million Hyper Suprime-Cam galaxies. We have used these catalogs to identify and investigate different evolutionary pathways for galaxies & AGN with varying morphologies.
