I am a 5th year graduate student in the UC Berkeley Astronomy Department, working under Aaron Parsons. I received my undergraduate degree from Haverford College in 2007, and an MPhil from the Cavendish Astrophysics Group at Cambridge University in 2008.

My primary research interests are in radio astronomy and cosmology. Presently, I am a member of the Precision Array for Probing the Epoch of Reionization (PAPER) team. PAPER is an interferometric array of low frequency dipoles designed to detect the highly redshifted 21cm signal from neutral hydrogen during the Epoch of Reionization. My work on PAPER has been in two main areas: instrument calibration and power spectrum analysis.
Repairing a PAPER dipole in the Karoo, South Africa. With Zaki Ali.
I am also a lead participant in the BAOBAB experiment to use the 21cm transition to detect netural hydrogen in galaxies at z~1. Our eventual goal is to detect the matter power spectrum and use Baryon Acoustic Oscillations to probe Dark Energy. Other research interests include galaxy clusters and the Sunyaev-Zel'dovich effect, observational probes of inflation, and anomalous microwave emission from spinning dust grains.
