Broadly speaking, my interests lie in the physics of and beyond today's standard cosmological model.
My main research concerns the processes in early galaxies
that enable a substantial fraction of their ionizing radiation to escape the dense interstellar medium,
which is crucial in understanding the Epoch of Reionization.
I have been involved in the Cosmology Large Angular Scale Surveyor (CLASS),
whose primary goal is to detect and characterize the primordial B-mode polarization of the Cosmic Microwave Background
-- a unique signature left by the primordial gravitational waves as posited in the theory of Inflation.
Before coming to Johns Hopkins, I worked on theoretical studies of large-angle anomalies
-- phenomena revealed by measurements of the microwave background that are statistically unlikely to occur in the standard model.
