    I am an astronomer, cosmologist, and data scientist. I am currently a NSF funded Research Associate in the MIT Program in Science, Technology and Society (STS) and a Visiting Research Scientist at the MIT Center for Theoretical Physics. I work on several theoretical and observational cosmology projects, including devising fun experiments that leverage cosmology to help test fundamental physics and observing exploding stars with ground and space based telescopes. Before MIT, I completed a PhD in Astronomy & Astrophysics from the Harvard University Department of Astronomy and I received my BA in Physics & Astrophysics from UC Berkeley. 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.
