Sophia graduated from MIT in 2011 with a B.S. in Mathematics with Computer Science (course 18c).
She is currently a cryptographer and software engineer at MIT Lincoln Laboratory.
She is also pursuing her graduate studies in Cryptography at Boston
University, where she is looking at new multi-party computation schemes,
as well as exploring authenticated data structures (specifically,
