    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.

Exploring the Multiverse
   Some leading cosmologists argue that it is no longer a question of whether other universes exist. It is simply a question of how many different levels there are to the so-called Multiverse. For example, almost all working cosmologists already accept the existence of regions of space beyond the accessible and observable part of the universe. These comprise distant regions which are so far apart from us that we could never reach them, even if we traveled at the speed of light forever, provided that general relativity is correct and that the expansion of our universe keeps accelerating forever. Other, more speculative, levels of the Multiverse have been discussed that are nonetheless straightforward logical extrapolations of our best theories of physics, which have been extremely well tested in other regimes. However, it remains a significant challenge to determine how to test theories that predict various types of Multiverse, especially because they might include regions that seem to be unobservable, in principle. This controversial topic thus represents an exciting area at the leading edge of theoretical physics.

I was selected to participate in the UC Santa Cruz Institute for the Philosophy of Cosmology, a 3-week summer workshop sponsored by the Rutgers Templeton Project in the Philosophy of Cosmology. Lecture videos are online under the “Program” link (Jun 23-July 14, 2013)

I was a Science Consultant for NOVA, The Nature of Reality, the physics blog of the PBS television station, WGBH Boston for Greg Kestin's video “4 Multiverses You Might Be Living In”, which discusses the controversial, but seriously discussed, idea of multiple universes in modern cosmology. Charles Q. Choi also wrote an excellent article about the multiverse accompanying the video.
