These are some of the papers that I have worked on:
The Maximum Likelihood Correlation Function Estimator Correlation functions are frequently measured in galaxy catalogs using pair counting techniques. We developed a new method for estimating the correlation function with pair counts that outperforms the standard Landy & Szalay estimator in certain regimes.
Primordial non-Gaussianity and reionization We show that primordial non-gaussianity leads to a scale dependence of the ionization field during reionization. We show that a futuristic 21 cm experiment can place tight constraints on non-Gaussianity.
Non-Gaussianity and Excursion Set Theory: Halo Bias Primordial non-gaussianity leads to a scale dependence of the halo bias. We showed how this result comes out of an excursion set formalism, and derived corrections that arrise when different collapse models are used.
A Robust Approach to Constraining Dark Matter Properties with Gamma-Ray Data Two of the main obstacles to the extraction of information about dark matter from gamma-ray data are the presence of large and uncertain gamma-ray backgrounds, and large uncertainties in the distribution of dark matter. Scott Dodelson and I developed a technique for extracting constraints on the properties of dark matter that is very robust with respect to these two uncertainties.
Constraining Dark Matter in Galactic Substructure. Work I did with Scott Dodelson at the University of Chicago. We explored the utility of the photon counts probability distribution function as a tool for indirectly detecting dark matter subhalos in our galaxy.
The Distance to NGC 2264. Work I did with Kevin Covey and August Muench at the Harvard-Smithsonian CfA REU program. By measuring the distribution of the inclination angles of stellar rotation axes, it is possible to constrain the distance to a cluster of young stars. We applied this novel technique to NGC 2264.
Modeling the Rotational Evolution of Young T Tauri Stars. Work I did with Ann Esin at Harvey Mudd College. We developed a simple model for the effects of magnetic locking between a T Tauri star and its accretion disk. Using this model, we generated artificial rotation period histograms for a cluster of T Tauri stars and showed that these compared favorably to observations.
