Tim Childers
Tim Childers was a freelance science journalist with a background in physics and science communication. He studied Physics at the University of Colorado Boulder, with his research focused on modeling the dynamics of the accretion disks surrounding black holes. He then went on to do an internship at the NASA Goddard Space Flight Center using his film talents to create videos, news stories, and interviews. Nowadays, Tim is an exceptionally curious data scientist who loves using data to tell stories to a diverse audience.
