  • Bryant York is a Distinguished Visiting Professor of Computer Science at Olin College of Engineering.  After receiving his A.B. in mathematics from Brandeis University, Dr. York received his M.S. in management from MIT and an M.S. and Ph.D. in computer science from the University of Massachusetts - Amherst. He has held industrial research positions at the IBM Research Labs in San Jose, CA and at Digital Equipment Corporation's Artificial Intelligence Technology Center in Hudson, MA. He retired in 2019 after 18 years as Professor of Computer Science at Portland State University; he was formerly associate professor and research director for the College of Computer Science at Northeastern University (1991 – 2001); and formerly associate professor of computer science at Boston University (1986 – 1990). During 1990-1991 he served as a program officer at NSF and as a guest researcher at the Center for Computing and Applied Mathematics at the National Institute of Standards and Technology (NIST).


Over the past thirty years Dr. York has worked diligently on broadening participation in computing with extensive service at the national level, including membership on advisory committees of the National Science Foundation, various boards and committees of the Association for Computing Machinery (ACM), the Computing Research Association (CRA) and the American Association for the Advancement of Science (AAAS).  In 1997 and 2000 he co-founded two institutes for dealing with African American aspects of the digital divide – African American Scholars for Citizenship and Community (AASCC) and the Institute for African American eCulture (IAAeC).  He is also co-founder of the Richard A. Tapia Celebration of Diversity in Computing conference series (2001, and co-founder and past board chair (2011 – 2015) of the Center for Minorities and Persons with Disabilities in Information Technology (CMD-IT,  Dr. York taught courses and lectured on parallel computing in China (2005 – 2010); he was a delegate to the First U.S.-China Computer Science Summit held in Beijing in 2006 and the follow-on summit held in Washington, DC in 2008.


Bryant’s current interests include quantum computation, post-quantum cryptography and asynchronous computing.
