Biography
Jordan Mirocha (he/him/his) is a Senior NASA Postdoctoral Program Fellow at JPL. His work focuses on the formation of galaxies in the early Universe and how to infer their properties using a variety of measurements including galaxy surveys, the high redshift 21-cm signal, and maps of the near-infrared sky. He earned his PhD in 2015 working with Jack Burns at the University of Colorado, where he developed models for the global 21-cm signal and used them to make predictions for upcoming experiments. In 2015, he moved to UCLA, where he worked with Steve Furlanetto on models of stellar feedback and used the latest results from Hubble to guide 21-cm model predictions. After moving to McGill in 2018, Jordan worked with Adrian Liu to develop new ‘hybrid’ reionization modeling techniques, as well as a new analytic model used to interpret data from the Hydrogen Epoch of Reionization Array. At JPL, Jordan is working with Tzu-Ching Chang and the SPHEREx team on isolating the emission of high redshift galaxies from nearby galaxies to constrain star formation in the early Universe.
