    I am an astronomer, cosmologist, and data scientist. I am currently a NSF funded Assistant Research Scientist at the UC San Diego Center for Astrophysics & Space Sciences (CASS profile) and a Research Affiliate in the MIT Program in Science, Technology and Society (STS). I work on several theoretical and observational cosmology projects to devise and implement fun experiments that leverage cosmology to help test fundamental physics. These include a series of experiments with colleagues to test quantum theory with astronomical observations as well as Infrared and Optical observations of Type Ia Supernovae with ground and space based telescopes, which can be used to measure the expansion history of the universe, cosmic acceleration, and dark energy. Before UCSD, I was an NSF Postdoctoral Fellow at MIT, a NSF Funded Research Associate at MIT, and a Visiting Research Scientist at the MIT Center for Theoretical Physics. I completed my PhD in Astronomy & Astrophysics from the Harvard University Department of Astronomy and I received my BA in Physics & Astrophysics from UC Berkeley. I am very interested in projects at the intersection between observational astronomy, astrophysics, data analysis, and the philosophy of science, especially the philosophy of cosmology. I am excited to explore a range of fascinating scientific questions through research, science writing, art, animation, public outreach, and working with the science media.

Animation 1 corresponds to Fig. 1 of Friedman+2013 for the case in which events A and B appear on opposite sides of the sky as seen from Earth (α = 180 degrees). The redshifts zA and zB of each event are changed in tandem to maintain the condition that their past light cones intersect at the big bang (τAB=0) at the end of inflation. The movie explores a portion of the parameter space in the zA-zB plane shown in Fig 3b of Friedman+2013; as zA and zB are changed while maintaining the condition τAB=0, each frame of the movie traces out a portion of the black curve in Fig 3b of Friedman+2013 corresponding to an angular separation of α = 180 degrees.
