About

I am a professor of astrophysics at Arizona State University. In the Low Frequency Cosmology lab, we observe high redshift cosmology at low radio frequencies, develop space-based astronomy and other interesting projects that take advantage of our unique skills. Our biggest projects include the Hydrogen Epoch of Reionization Array (HERA), the Precision Array for Probing the Epoch of Reionization (PAPER) in South Africa, and the Murchison Wide-field Array (MWA) in Western Australia, the SPARCS cubesat, and the DORA cubesat. I am also Associate Director of the ASU Interplanetary Initiative where I serve as Director of the Interplanetary Lab which supports cubesats and other small space missions.
