Glenn Stevens has been Director of PROMYS since he co-founded the program in 1989. He is Professor of Mathematics at Boston University where he has taught and conducted research since 1984. He earned his Ph.D. in Mathematics from Harvard University in 1981. His research specialties are Number Theory, Automorphic Forms, and Arithmetic Geometry. He has authored or edited three books and published numerous articles on these topics. Professor Stevens has organized two major research conferences including the Conference on Modular Forms and Fermat's Last Theorem held at Boston University in 1995. Professor Stevens is Principal Investigator of the NSF-funded Focus on Mathematics Math and Science Partnership and co-Principal Investigator of the NSF Noyce grant, Math for America Boston: Teaching Scholars Program. He is also President of Math for America-Boston. Glennfest, a Conference on p-adic Variation in Number Theory, was held at Boston University on June 2-6, 2014 to celebrate Professor Stevens' 60th Birthday. 

Li-Mei Lim, the Assistant Director of PROMYS, is Visiting Lecturer in Mathematics at Boston University. After earning her PhD in Mathematics from Brown University in 2013 with a specialty in Analytic Number Theory and Automorphic Forms, Professor Lim taught at Boston College and at Bard College at Simon’s Rock. Professor Lim attended PROMYS as a student in 2001 and 2002, as a junior counselor in 2003 and 2004, as a counselor in 2005 and 2006, and as Head Counselor in 2007 and 2008. Since then, she has returned in multiple capacities including as a PROMYS Guest Lecturer and as a T^2 for PROMYS for Teachers. One of the founders of the PROMYS Foundation, Professor Lim has been on its Board of Trustees since its inception in 2011. 

Henry Cohn is a principal researcher and one of three founding members of Microsoft Research New England, as well as an adjunct professor of mathematics at MIT. He received his Ph.D. in mathematics from Harvard in 2000 under the supervision of Noam Elkies. Professor Cohn's mathematical research interests are in discrete mathematics, including discrete geometry, coding theory, cryptography, combinatorics, computational number theory, and theoretical computer science.  He was a student at PROMYS in 1990, junior counselor in 1991, counselor in 1992–1995, and head counselor in 1996. PROMYS has greatly benefited from his presence during multiple summers as instructor, research mentor, and guest lecturer. Professor Cohn is a trustee of the PROMYS Foundation, which he co-founded with other alums in 2011.

Marjory Baruch teaches mathematics and computer science at Syracuse University and has taught at PROMYS every summer since its founding in 1989. She received her Ph.D. from the University of Pennsylvania. She is a Trustee of the PROMYS Foundation.

David Fried is Professor of Mathematics at Boston University and co-founded PROMYS. He has taught at PROMYS every summer since its inception in 1989. He received his PhD from the University of California, Berkley in 1976. His research interests are dynamical systems, topology, and differential geometry.

Steven Rosenberg, who is Professor of Mathematics at Boston University, has taught in the PROMYS program every summer since 1991. His research interests are in differential geometry in finite and infinite dimensions, particularly with applications to/from mathematical physics. He is the author of the book, "The Laplacian on a Riemannian Manifold" aimed at graduate students.

Visiting Mathematicians and Alumni


PROMYS Community

PROMYS has been sustained and enriched over the past 30 years by a belief that math is a deeply human activity best experienced within a richly interacting and mutually supportive community of learners including high school students, undergraduate and graduate students, teachers, and research mathematicians. For six summer weeks, over one hundred mathematicians wrestle joyfully with math. Often for the first time in their lives, talented young people tackle math that is beyond their immediate grasp; are exposed to math which is beautiful and daunting; are held to exacting standards of rigor and precision; meet others with the same level of talent and passion; and learn, not just as students, but as scientists. PROMYS is non-competitive and students learn from each other.  

The advanced students and counselors help create a deeply rich mathematical environment for each other and for the first-year students by offering seminars, minicourses, and lectures to augment those of the faculty and of the guest lecturers. Similarly, it is crucial that the PROMYS students witness older students, counselors, and adult professionals engaging actively, intensely, collaboratively, and joyfully in creative mathematical endeavors. PROMYS proves to participants that many of the pervasive math stereotypes are inaccurate. They see for themselves that math is a creative and collaborative enterprise, that mathematicians can be engaging and happy, that there is a vibrant community they can choose to join, that math need not be a solitary activity, and that members of the community give each other social and intellectual support. Many alumni have told us that this exposure revolutionized their attitude towards having a career in math. They say they came first for the math, and they returned for the people.
