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 in Jefferson Lab, at Harvard Physics. I got my PhD from Johns Hopkins University, under the supervision of Marc Kamionkowski, and I've had the pleasure to work with Cora Dvorkin, Avi Loeb, and Daniel Eisenstein while at Harvard.

I work on the intersection of particle physics and astrophysics. Recently, I have focused on 21-cm cosmology, both as a new dark-matter probe and as a standard ruler (using velocity-induced acoustic oscillations, or VAOs). My interests also include inflation, gravitational lensing, fast radio bursts, dark matter, large-scale structure, neutrino masses, and the cosmic microwave background.

You can find my full CV here, and my publications in
