I am a cosmologist working at the intersection of theory, algorithms, and big data. Our research group focuses on answering fundamental questions about our Universe using the largest 3D maps of it ever made: spectroscopic (redshift) surveys of galaxies, such as SDSS BOSS, DESI, and Roman. 

We develop tools to bring within computational reach questions we have as yet been unable to ask. 

We have pioneered algorithms to measure the 3, 4, 5, and 6-Point Correlation Functions of galaxies, and advanced methods to handle their systematic and statistical errors. We have broken ground on new signatures of standard and non-standard physics that can be sought with these correlations, ranging from neutrino mass to axion physics to parity violation (breaking of mirror symmetry). 

We have also worked to expand the mathematical tools available to us for cosmology, and, in parallel, to accelerate algorithms for currently standard-but-expensive problems.

We are currently a vibrant group of four graduate students, a post-doc, and five undergraduates, as well as several frequent external collaborators, and you can find a list of students who have worked with our group (13!) in the past under Alumni.

We hope you will enjoy exploring our work!
