Dr. Gourav Khullar is a Baum Postdoctoral Fellow for Innovative Astronomy at the University of Washington, USA. He finished his PhD in 2022 from the Dept of Astronomy & Astrophysics, and Kavli Institute for Cosmological Physics (KICP), at the University of Chicago. He works on studying mass assembly and the cessation of star formation in the earliest galaxies in the Universe, by using observations from ground- and space-based facilities like Magellan, Gemini Telescopes, Nordic Optical Telescope, Hubble and JWST, as well as the phenomenon of gravitational lensing. He leads two JWST General Observer programs to study massive and bright gravitationally lensed systems at cosmic noon and beyond, and his group at UW is excited about utilising space telescope data to study the zoomed-in regions of these distant galaxies.
