Achilleas Porfyriadis received his B.S. in 2010 from MIT and his PhD in 2016 from Harvard. Thereafter, he was a postdoctoral scholar at the University of California, Santa Barbara prior to joining the Black Hole Initiative in 2019. His research interests are in theoretical gravitational physics and he is interested in both classical and quantum aspects of gravity. He is using gravitational techniques from holographic dualities to inform the study of astrophysical black holes. The approach has rendered feasible a large number of analytic computations of relevant black hole processes that could not otherwise be performed, sometimes not even numerically.
