PhD Candidate
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, accumulator constructions).
Sophia has an Erdös number of 4. (She co-authored with Emily Shen, who co-authored with Ron Rivest, who co-authored with Nathan Linial, who co-authored with Paul Erdös.)
