About

I am currently working with the DiRAC Institute at the University of Washington to develop and test Hyrax, an Astro-Machine Learning framework, by looking for anomalous and rare objects in large astronomical datasets.

I'm also a member of the Meg Urry Lab here at Yale, and my research involves doing near-infrared spectroscopy of high-redshift Fermi blazars using Hβ and Mg II λ2800 lines. My previous project (published paper) involved spectroscopy of variable z < 1.5 AGN, using their properties such as mass and brightness to study the black hole-host galaxy mass evolution.

Beyond my research, I serve as a Head of Consulting for Elmseed Consulting and as the Events and Communications Chair for the Yale Astronomical and Space Student Society (YASSS).

Research

Current

DiRAC Institute, University of Washington

Rare-object discovery with Hyrax

Train and benchmark models (CNNs,convolutional autoencoders/DCAE, SimCLR) for Hyrax – an astronomy ML framework – on ~6,000 realistic HSC-simulated IllustrisTNG subhalo images.

  • Methods: dimensionality reduction, clustering, model evaluation
  • Link: Hyrax project
Current

Meg Urry Group, Yale

High-redshift Fermi blazars in the near infrared

Using H-beta and Mg II 2800 line measurements to study high-redshift Fermi blazars and extend the spectroscopic picture of these sources.

  • Methods: NIR spectroscopy and line-based inference
Published

Astrophysical Journal

DAVOS: variability-selected AGN in DES deep fields

Studied variability-selected AGN at z < 1.5, using mass and brightness measurements to examine black hole and host galaxy mass evolution.
