Welcome! 

I am an Astrophysicist at the Center for Astrophysics | Harvard & Smithsonian (CfA). I primarily work on the Event Horizon Telescope (EHT) to study black holes through direct imaging. I am also working with an exceptional team to develop a new mission, the Black Hole Explorer (BHEX), that will extend the EHT into space to detect a black hole’s photon ring for the first time.

See my research page for more details on these projects. You can access my papers here on ADS.
