My research seeks to discover the physics of cosmic inflation and cosmic acceleration by predicting and measuring their signatures in cosmological surveys. I have used data from both cosmic microwave background surveys and galaxy surveys to find new ways to combine multiple datasets, in order to break degeneracies between various properties of our universe. Much of my work has also helped motivate the use of intensity mapping, a new probe of large-scale structure in which emission of the 21-cm line from neutral hydrogen as well as other spectral lines is mapped across the sky at very high redshifts, allowing cosmologists to fill in the evolutionary gap between the early and late universe.
