I am a Ph.D. candidate and NASA FINESST Fellow working with NASA GSFC & UMD Researcher Dr. Anna Ogorzalek and UMD Prof. Christopher Reynolds. My research focuses on analyizing high-resolution X-ray spectroscopy with advanced statistical and computational methods to study highly ionized Active Galactic Nuclei (AGN) outflows and their connection in AGN feedback. I primarily use data from Chandra X-ray Observatory, XMM-Newton, and XRISM.

I received my M.S. in Astronomy from the University of Maryland, College Park in 2023. I graduated from the University of California, Los Angeles with a B.S. in astrophysics after transferring from Irvine Valley College.
