Broadly speaking, my research spans from testing the standard ΛCDM model of cosmology to understanding the evolution of galaxies.
Currently, I work on two topics: diagnostics of the escape of ionizing radiation and galactic outflows.
The former concerns the processes in early galaxies that enable a substantial fraction of
their Lyman-continuum radiation to escape the dense interstellar medium, which is crucial in understanding the Epoch of Reionization.
The latter is on the physical processes governing starburst-driven outflows, which are often invoked as the principal feedback mechanism in models of galaxy formation and evolution.
Previously, 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 ΛCDM.
