Bevin Maultsby
Bevin is a teaching professor at NC State University who enjoys helping students build confidence and curiosity. She has a Ph.D. in Mathematics from UNC Chapel Hill, where she also earned undergraduate degrees in Mathematics and French. Bevin first worked with talented younger students during her postdoctoral position with MathCEP at the University of Minnesota, where she helped create mathematical experiences outside classroom settings.
She now teaches university-level mathematics and creates online math videos viewed by students around the world. Bevin guides students to see that math is not about memorizing rules, but about asking good questions, noticing patterns, and learning how to think carefully. Besides teaching, Bevin also enjoys traveling and learning new languages.
Meg Millard
Meg has been an educator and organizer of young people for most of her life, including as a teacher, nature museum manager, and organic farmer. As an elementary and middle school teacher for over thirty years in public, charter, and independent schools, she is an advocate for Project Based Learning to guide students in integrating and applying their skills in meaningful ways. Meg has a B.A. in Environmental Studies and a Masters degree in K-8 Mathematics. She is certified in Elementary Education (K-5 & 4-6), K-8 Mathematics, 6-8 Language Arts, and Environmental Education. She loves sharing her love of learning with her students.
Andrew Prudhom
Andrew has taught mathematics at the Durham Academy Upper School since 2018, where he enjoys the freedom to offer "kooky electives" on the more esoteric mathematics he grew to love during his own math education. After dropping out of high school and working a factory job for a few years, he enrolled in a local community college and began what ended up as a ten-year love affair with mathematics. In that time he went from a mathematical layman to successfully defending a Ph.D. in pure mathematics from UNC Chapel Hill. Having had the opportunity to interact with the beautiful mathematics that are traditionally hidden away in the ivory tower, he is passionate about bringing that sort of math to mainstream audiences. At Durham Academy he specializes in teaching "high-level mathematics" at the high school level, and so far has taught classes in Logic, Discrete Mathematics, Topology, and Number Theory, all of which he teaches only requiring a basic algebra course as prerequisite.
Maria Droujkova
Maria focuses her research and development efforts on learning communities, informal education, online education, and game design. She holds a Ph.D. in Mathematics Education from NCSU, and M.S. in Mathematics from Tulane University. Maria is the founder of Natural Math, an educational design, consulting, and publishing organization started in 1996. In 2020, Maria co-founded the 501(c)(3) non-profit Natural Math Alliance. Maria works on community-responsive projects, family mathematics, and making all mathematics accessible to everyone in kind ways. She co-authored Moebius Noodles and Avoid Hard Work, popular books with innovative mathematical activities for parents, teachers, and math circle leaders.
Danny Nguyen
Danny is a parent of several Mathematics Institute students. He holds B.S. and M.S. degrees in Electrical & Computer Engineering from Georgia
