Biography

Dr. Finkelstein graduated with a B.S. from the University of Washington, Seattle, in 2003, and with a Ph.D. from Arizona State University in 2008. After graduating, he conducted research at Texas A&M University as the Postdoctoral Research Associate from 2008-2011. Dr. Finkelstein started as an Assistant Professor at the University of Texas at Austin in 2012, and became an Associate Professor in 2017. His research group's studies include: First Stars & Galaxies, Reionization Era & First Galaxies, Stellar Populations, Star Formation (Extragalactic), HETDEX: Dark Energy Experiment.

Research

Dr. Finkelstein's research group seeks to understand when and how galaxies first formed out of the cosmic dark ages. How long after the Big Bang did it take for the first stars to ignite? What were the properties of the first galaxies, and how do they differ from our Milky Way? How were the earliest black holes seeded and how did they grow? How did galaxies and accrediting black holes contribute to the reionization of the intergalactic medium?

He focuses on answering these questions through observations with state-of-the-art telescopes, including the largest telescopes on the ground and JWST and Hubble in space. They aim to achieve a physical understanding by interpreting our data through vibrant collaborations with theoretical astrophysicists from many groups around the world.

The research group collaborates within the Cosmic Frontier Center, designed to combine the observational and theoretical expertise in early galaxy formation at UT Austin to make breakthrough discoveries. The research group includes several postdocs and graduate students, each working on different pieces of the puzzle, often working together to acheive their goals. Recently their key effort has been the JWST CEERS project.
 

Dr. Finkelstein's research interests include: Observations of the Early Universe; Galaxy Formation and Evolution; Reionization; Chemical Evolution of the Universe.
