Randal Bryant

Randal E. Bryant (born October 27, 1952) is an American computer scientist and academic noted for his research on formally verifyingdigital hardware and software. Bryant has been a faculty member at Carnegie Mellon University since 1984. He served as the Dean of the School of Computer Science (SCS) at Carnegie Mellon from 2004 to 2014. Dr. Bryant retired and became a Founders University Professor Emeritus on June 30, 2020.

Bryant has received many recognitions for his research on hardware and software verification as well as algorithms and computer architecture. His 1986 paper on symbolic Boolean manipulation using Ordered Binary Decision Diagrams (BDDs) has the highest citation count of any publication in the Citeseer database of computer science literature.^[1] In 2009 Bryant was awarded the Phil Kaufman Award by the EDA Consortium "for his seminal technological breakthroughs in the area of formal verification."

Bryant was born on October 27, 1952, and is the son of John H. Bryant and Barbara Everitt Bryant, and the grandson of William Littell Everitt, former dean of the electrical engineering department at the University of Illinois at Urbana–Champaign (1949–68). His sister is Lois Bryant, a textile artist. Bryant was raised in Birmingham, Michigan. Starting in 1970, he attended the University of Michigan, where he received his B.S. in applied mathematics in 1973. His master thesis on Simulation of Packet Communication Architecture Computer Systems, published in 1977, is known to be one of the first publications on distributed simulation.^[2] He received his PhD from the Massachusetts Institute of Technology in 1981.^[3]

• From 1981 to 1984, Bryant was assistant professor of computer science at California Institute of Technology. His research areas included VLSI circuit models, logic simulation, and circuit testing. He also taught courses in computer architecture, digital systems theory, and computer algorithms.
• In 1984, Bryant joined the faculty at Carnegie Mellon as an assistant professor of computer science. He continued his research on VLSI simulation, VLSI circuit verification, symbolic manipulation, and parallel computation.

• Over the past years, Bryant has done much research on formal hardware and software verification as well as computer systems. His most well-known publication^[6] in 1986 was "Graph-Based Algorithms for Boolean Function Manipulation", in which binary decision diagram (BDDs) was presented as a novel data structure for representing Boolean functions and manipulation algorithms. BDDs has been used extensively in fields such as digital circuit testing and synthesis and artificial intelligence planning. According to the famous Computer Scientist Donald Knuth, BDDs was deemed as "one of the only really fundamental data structures that came out in the last twenty-five years".^[2] Following his research, he published another paper^[7] on a tutorial and update on BDDs in 1992. His paper on BDDs was awarded for having the highest citation count in the Citeseer database of any computer science literature.^[1]
• His work in verifying digital circuits-seminal work has received numerous awards from IEEE and other professional societies (see below). His paper on Formal verification by symbolic evaluation of partially-ordered trajectories^[8] was published in 1995. The method of symbolic trajectory evaluation described in his paper has been widely adopted to the industry, notably used by Intel.^[3] Starting in 2004, Bryant has been promoting new research initiatives in data-intensive computing.
• Bryant and Professor David R. O'Hallaron at Carnegie Mellon University together wrote the book "Computer Systems: A Programmer's Perspective," in which they take a novel approach on teaching computer systems. Rather than emphasizing the design and implementation of the systems, the book focuses on teaching students how systems - architecture, compilers, operating systems, and computer networking - affect the behavior and performance of the program. This book, now in its third edition, has been translated into Korean, Chinese, Macedonian and Russian and is in use by institutions all over the world.^[9]
