PROGRAM- The History of the Universe: From the Big Bang to Beer
By: Dr. Benjamin Keller, Assistant Professor, Department of Physics and Materials Science, University of Memphis

We stand today looking back at nearly 14 billion years of cosmic history. In that time, our universe has changed immensely, from simple beginnings to a universe filled with complexity. In this talk, Ben takes us on a tour of the major changes that have taken the universe from it’s hot, uniform beginnings to one filled with stars, planets, to the life that lives on this planet. In this tour, we see now only what we know about our universe’s history, but also how we know it.

Dr. Keller is a numerical astrophysicist, with a primary interest in the formation and evolution of galaxies. His research uses some of the world's largest supercomputers to simulate the gravitational collapse of gas and dark matter in the early universe, building up the structures we see today.

Dr. Keller joined the University of Memphis Department of Physics in Fall 2022. He earned his BS in Physics and Computer Science from the University of Calgary in 2011, and his PhD in Physics from McMaster University in 2017, supervised by Dr. James Wadsley. After completing his PhD, he moved to Heidelberg, Germany as an Alexander von Humboldt Postdoctoral fellow from 2017-2020, followed by a postdoctoral researcher appointment in Dr. J.M. Diederik Kruijssen's research group at the Ruprecht-Karls-Universität Heidelberg.
