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

I am a theoretical cosmologist at Harvard. Recently, I have been working 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.

I got my PhD from Johns Hopkins University, under the supervision of Marc Kamionkowski. I am now a Postdoctoral Fellow in the Harvard Physics department, working with Cora Dvorkin and Avi Loeb. You can find my full CV here, and my publications in
