Welcome

Hi, I'm Julian. Welcome to my page!

I am a long-term Clay fellow at the Harvard-Smithsonian Center for Astrophysics. Before that I was a postdoctoral fellow at the Harvard Physics Department. I got my PhD from Johns Hopkins University in 2017, under the supervision of Marc Kamionkowski.

My work is at the intersection of particle physics and astrophysics. Recently, I have focused on learning about cosmology, galaxy formation, and dark-matter microphysics from the first galaxies. This includes using UV LFs from Hubble as well as the 21-cm line of hydrogen. I have developed the latter both as a new dark-matter probe and as a standard ruler (using velocity-induced acoustic oscillations, or VAOs). My interests also include gravitational lensing, the large-scale structure, light relics, primordial black holes, fast radio bursts, and the cosmic microwave background.
