Tom Shrimpton is an associate professor in the Department of Computer Science at Portland State University. His research is in cryptography, with an emphasis on the theory and practice of hash functions, authenticated encryption, and other symmetric-key primitives. Recently, he has worked more broadly in applied cryptography. He earned a Ph.D. in 2004 from the University of California (Davis) under Phillip Rogaway. In 2009, Professor Shrimpton was the recipient of a National Science Foundation CAREER award.

In 2013-2014, he worked on a technology called "Format-transforming encryption" with his student Kevin Dyer, and collaborators Scott Coull and Tom Ristenpart. For this, they were awarded a generous gift from Google Executive Chairman Eric Schmidt.
