Presently I’m interested in observational studies of exoplanets, debris disks, and their host stars. One of my favorite parts of this job is giving research talks! One of my long-term goals is to become a research professor.

I was born in San Antonio, Texas where I lived until moving to Hawai’i for graduate school. I did my undergraduate studies at UT San Antonio. My journey as a scientist truly began when I worked as a TAURUS Scholar at UT Austin in the summer of 2017. Here I worked with Dr. Brendan Bowler to measure the dynamical mass of HR 8799. I also worked as a NSF REU student at the Center for Astrophysics | Harvard & Smithsonian in the summer of 2018. Here I worked with Dr. Luca Matrà on the REsolved ALMA and SMA Observations of Nearby Stars (REASONS) Survey, where I characterized the HD 170773 debris disk using ALMA.

I’m a first-generation college student with interests in student success initiatives, including effective mentoring.


Fun Facts:

Before finding my calling in science, I considered a career in law/politics.

I once participated in joint classroom learning sessions with incarcerated participants at a state jail.

My favorite band is probably Darkthrone.
