    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.

Andrew Friedman: Bio
   I am currently working with MIT Physics Department Faculty, including Professors David Kaiser and Alan Guth, in the MIT Program in Science, Technology and Society and the MIT Center for Theoretical Physics (CTP). Along with Jason Gallicchio (Harvey Mudd Physics), Brian Keating (UCSD CASS), Anton Zeilinger (Vienna IQOQI), and collaborators, we are developing and implementing a series of experiments that test quantum mechanics and entanglement with the help of astronomical observations. Specifically, we are aiming to close one of the last remaining loopholes in tests of Bell's inequality that could allow a so-called local hidden variable theory to mimic the predictions of quantum mechanics. See here for more on our proposed “Cosmic Bell” experiments including our experimental proposal paper, a popular description, and a paper on our first successful experiment. Our work is being funded through the NSF INSPIRE program, via NSF Award #1541160 (2015-2018). Previously at MIT, I was a NSF STS Postdoctoral Fellow, supported by NSF Award #1056580 (2012-2014).

   My PhD thesis project with Professor Robert Kirshner was on Infrared Light Curves of Type Ia Supernovae. Type Ia Supernovae can be used as standardizable candles for cosmology to measure the expansion history of the universe and constrain the mysterious dark energy thought to be causing the acceleration of cosmic expansion. The supernova aspect of the project used infrared data obtained with the fully robotic 1.3 meter Peters Automated Infrared Imaging Telescope (PAIRITEL) at the Fred Lawrence Whipple Observatory on Mount Hopkins, Arizona (P.I. Professor Joshua Bloom, UC Berkeley). See here for more on infrared observations of Type Ia and other types of Supernovae. I am also currently a Co-Investigator on observational programs with the Hubble Space Telescope (PI R. Kirshner and collaborators) which observe Type Ia Supernovae at cosmological distances in the near-infrared (RAISIN, Cycle 20, #13046, RAISIN2, Cycle 23, #14216).

   My previous work with Professor Ramesh Narayan and Professor Joshua Bloom focused on testing the potential applications of Gamma-Ray Bursts (GRBs) for cosmology by studying GRB spectra and energetics. This work formed the basis of my graduate research exam project and my Harvard Master's thesis. My work has been supported in part by a National Science Foundation Graduate Research Fellowship and a NASA Graduate Student Research Program Fellowship, where I collaborated with researchers at the NASA Goddard Space Flight Center in Greenbelt, Maryland, including Dr. Neil Gehrels, the Principal Investigator of the NASA Swift Satellite, a space experiment that studies both GRBs and supernovae. See here for more on using GRBs for cosmology.

   At UC Berkeley, I did my undergraduate Astronomy thesis on supernova light curves with Prof. Alex Filippenko.

   A reasonably up to date list of my publications is here or on NASA/ADS.
