Jonathan Pritchard

My academic journey began with an undergraduate degree in Natural Sciences from Cambridge. I then moved out west to study for a PhD in the Theoretical Astrophysics group at the California Institute of Technology. From there I migrated east as a Hubble Fellow at the Harvard-Smithsonian Center for Astrophysics. In 2011, I joined the Physics department at Imperial College London as a lecturer in Astrostatistics. My research addresses the first billion years after the big bang, focussing on the period when the first generations of stars and galaxies formed. I'm particularly interested in the possibility of using new radio frequency observations with telescopes like LOFAR and the Square Kilometer Array to learn about this period.
