Andrew Chael is a theoretical astrophysicist who studies the near-horizon environments of black holes. He received his PhD from Harvard University in 2019. Before joining the NBIA, he was a NASA Einstein Fellow at the Princeton University Center for Theoretical Science and a Fellow at the Princeton Gravity Initiative. He was awarded a Villum Young Investigator Grant to build a group in near-horizon black hole astrophysics at the NBIA in 2025. 

Andrew works to understand the dynamic environments around supermassive black holes, where gravity, plasma, and magnetic fields interact to fuel accretion and drive relativistic jets across millions of light-years. By linking observations — including the first resolved images of black holes from the Event Horizon Telescope — to theory and numerical simulations, Andrew develops new techniques for probing fundamental physics and measuring black hole properties from radiation emitted near the horizon.
