    I am an astronomer, cosmologist, and data scientist, currently a NSF funded Assistant Research Scientist at the UC San Diego Center for Astrophysics & Space Sciences (CASS) and a Research Affiliate in the MIT STS Program. I work on several theoretical and observational projects to devise and implement fun experiments that leverage cosmology to test fundamental physics, including novel tests of quantum theory with astronomical observations as well as Infrared and Optical studies of Supernovae with ground and space based telescopes to measure the expansion history of the universe, cosmic acceleration, and dark energy. I enjoy exploring fascinating scientific questions at the intersection between observational astronomy, astrophysics, data analysis, and the philosophy of science through research, science writing, art, animation, public outreach, and science media engagement.
