Pronouns: he/him
I hold the Baum Fellowship For Innovative Astronomy at the Dept of Astronomy, and a Data Science Postdoctoral Fellowship in the eScience Institute, as of Fall 2024.
I work on understanding the mechanisms that cause quenching in the Universe’s first galaxies. I conduct this work with global and spatially resolved observations of dead and dying galaxies with the combination of space telescopes and lensing. JWST is where the action is these days!
Previously, I was a Samuel P Langley PITT PACC Astrophysics Postdoctoral Fellow at the University of Pittsburgh, USA, for two years. I received my PhD in Astronomy and Astrophysics at the University of Chicago in 2022, where I worked on understanding the properties of quenched systems in galaxy clusters, as well as bright galaxies gravitationally lensed by the very same clusters.
I am a teacher, instructor, mentor and advisor to graduate and undergraduate students. As part of my work and learning, I strive to incorporate inclusive pedagogy in my interactions and communication with my students, both in the classroom and in a research setting.
My community work in Astronomy has taken many directions, including science communication with Astrobites for 7 years. These days, I am primarily focused on equity, inclusion and justice work in my local communities. Academic departments often have local problems, requiring local solutions, that complement cross-institutional and global efforts. I see my work as helping organize the former at the grassroots level, while learning from the latter.
