Michael Barrus is an associate professor in the Department of Mathematics at the University of Rhode Island (URI). He received his undergraduate degree from Brigham Young University (BYU) in Provo, UT, and his Ph.D. in mathematics from the University of Illinois at Urbana-Champaign in 2009; he also has a masters degree in mathematics teaching. His research so far has principally fallen in graph theory, though he is also interested in other areas of combinatorics. He has written a number of research articles focusing on how simple local rules in graphs can have big impacts on the global structure, and he is an active participant in the combinatorial community in the Northeast. At a few different institutions in the U.S., Dr. Barrus has supervised several undergraduate honors and research projects in mathematics. He has also supported high school students by helping to found the Black Hills Math Circle in Spearfish, SD and serving as its Co-Director for a year, as well as being a session leader and instructor at BYU's math circle and math camp while he was a visiting professor there. Here at URI, he has served as a a co-principal investigator on a federally funded program for scholarships in STEM and as a mentor for scholarship recipients in math. He currently serves as a webmaster for the Northeastern Section of the Mathematical Association of America (MAA) and hold memberships in the MAA, the American Mathematical Society (AMS), and the Society for Industrial and Applied Mathematics (SIAM).
