**Dr. Diana White** is the Director of the National Association of Math Circles, a position she assumed in November 2014 after serving as a member of the NAMC leadership team for several years.

Dr. White has extensive experience with organizing, facilitating, evaluating, and researching Math Circles. She is the founding director of the well-established and highly successful Rocky Mountain Math Circle Program, which is now in its seventh year. Since its program launch in 2010, summer and academic year sessions have reached approximately 450 teachers throughout Colorado. Conservatively estimating that each year each teacher reaches 100 students, nearly 125,000 K-12 students have been affected by this program. She has long been significantly involved with the Math Teachers’ Circle program at the national level, partnering with the American Institute of Mathematics as co-PI of a National Science Foundation Discovery Research K-12 grant to study the program’s impact and acting as an external evaluator for other Math Teachers’ Circles. She also has experience facilitating the “How to Run a Math Teachers’ Circle” workshop. She regularly travels to other Math Teachers’ Circle across the country as an invited facilitator.

Dr. White received her Ph.D. in commutative algebra from the University of Nebraska at Lincoln in 2007. After a postdoctoral position in mathematics at the University of South Carolina, she joined the faculty of the University of Colorado Denver as her department’s first mathematician specializing in mathematics education. She has been involved with Math Circles since 2008.

**Dr. Jane Long** is an Associate Director of the National Association of Math Circles focusing on the Math Circles Mentorship and Partnership (MC-MAP), a position she assumed early in 2017 after serving as a mentor in that program for multiple years. As the founder and director of the East Texas Math Teachers’ Circle, which began meeting in 2013, she has recent and relevant experience starting and continuing a Math Circle. Her Math Circle has engaged in successful and unique partnerships with other organizations, providing professional development for teachers in long-term grant projects through federal grant programs such as GEAR-UP and the NSF Noyce Program, and the Texas Regional Collaborative program through Texas’s Region 7 Educational Service Center. Dr. Long regularly visits Math Circles for students and teachers as an invited facilitator and frequently engages in outreach activities related to problem solving for people of all ages and levels.

Dr. Long received her Ph.D. in algebraic topology from the University of Maryland at College Park in 2008. She has been on the faculty of Stephen F. Austin State University since that time and currently holds the rank of associate professor of mathematics.
