Personal website of Simon Birrer

I am a cosmologist using observations of our Universe to answer fundamental questions in physics. I am an Assistant Professor at Stony Brook University and a member of the Astronomy and Cosmology Group.

My scientific expertise is the interface between the exquisite data sets available on one side and the fundamental theory predictions on the other side. I am actively developing advanced computational and statistical tools and am an advocate for open-source and reproducible science.

Before joining Stony Brook, I was a Kavli Postdoctoral Fellow at Stanford University and a Postdoctoral Scholar at University of California, Los Angeles (UCLA). I received my PhD at ETH Zurich.
