Randal Bryant

Randal Bryant is a Professor of Computer Science at Carnegie Mellon University and a leading researcher in computer systems, particularly in the areas of hardware verification and symbolic computation. During his career, Bryant developed the Binary Decision Diagram (BDD) data structure and associated algorithms, which revolutionized digital circuit design and verification. His work on BDDs became fundamental to modern electronic design automation tools and formal verification methods. Bryant co-authored the widely-used textbook "Computer Systems: A Programmer's Perspective" with David R. O'Hallaron, which has become a standard reference in undergraduate computer science education. The book has been translated into multiple languages and adopted by universities worldwide. His contributions to computer science have been recognized with numerous awards, including membership in the National Academy of Engineering and the IEEE Emanuel R. Piore Award. Bryant served as Dean of the School of Computer Science at Carnegie Mellon University from 2004 to 2014.
