I am an astrophysicist and assistant professor in MIT's Physics Department and at the MIT Kavli Institute for Astrophysics and Space Research. In my research, I investigate how black holes form and evolve across cosmic time, exploring their origins and the role they play in shaping our universe. My work is particularly focused on the epoch known as the Cosmic Dawn, when the first stars, galaxies, black holes, and quasars begin to emerge.

In my research, I explore the Cosmic Dawn of our universe - the epoch when the first galaxies and black holes formed in the very early universe. I use observatories located all around the world and in space as “time machines” to capture the light from the most distant objects known to trace their origin and evolution, and piece together our cosmic history. I am particularly interested in how black holes in the early universe are able to grow and become very massive in short amounts of cosmic time.
