Csaba Biro

Csaba Biro is an Associate Professor of mathematics at the University of Louisville. He received his PhD from Georgia Institute of Technology in 2008. His research interests are combinatorics of partially ordered sets, graph theory, and geometry. He has taught mathematically talented 6th graders in Hungary to prepare them for an intensive mathematics magnet program.

Danielle Champney

Danielle Champney is an assistant professor of mathematics at Cal Poly, San Luis Obispo. She received her Ph.D. from UC Berkeley in Undergraduate Mathematics Education, after completing undergraduate and masters degrees in Applied Mathematics and Statistics. Danielle's primary research interests are twofold: the study of how students connect their understanding of mathematics, physics, and engineering at all grades and ages; and the study of how students use visual images when problem solving and learning new topics in calculus. She is also active in cultivating middle-high school/undergraduate partnerships with Cal Poly and partner schools, with an emphasis on building mentorship opportunities between college and pre-collegiate students, and works with students and teachers of all ages to promote active learning in math classes from grades K through 16+.

Tom Edgar

Tom Edgar is an associate professor of mathematics at Pacific Lutheran University in Tacoma, Washington. He received a Ph.D. from the University of Notre Dame after beginning his advanced studies at Colorado State University. His mathematical interests lie in the areas of algebraic combinatorics and the representations of Coxeter groups. More recently he has been interested in number theory as related to integer sequences and visualizing mathematics. He has worked closely with undergraduates on a number of summer research projects and is enthusiastic about working with future mathematicians of all ages.

Aaron Hill

Aaron Hill is an assistant professor of mathematics at the University of Louisville. He received a PhD in mathematics and a masters degree in curriculum and instruction at the University of Illinois at Urbana-Champaign. His research interests include mathematical logic, dynamical systems, and combinatorics. He also works closely with prospective elementary school teachers and has taught mathematically talented students at the elementary school level (in Illinois and Kentucky), middle school level (in New York), and high school level (in Texas). He is very excited to be working with 7- and 8-year-olds at Epsilon Camp.

Gabriel Sosa

Gabriel Sosa is a Visiting Assistant Professor at Amherst College. He worked as a Middle/High School teacher in Costa Rica for eight years before pursuing a graduate career as a Mathematician. He received his PhD from Purdue University in 2015. His research interests include Combinatorial and Computational Commutative Algebra, Graph Theory and Mathematics Education. He trained the teams that represented Costa Rica in the Iberoamerican Mathematical Olympiads in 2000, 2001 and 2002, and the International Mathematical Olympiads in 2006 and 2007.

David Wright

David Wright is an emeritus professor of mathematics at Brigham Young University. He received the MAA Intermountain Section Distinguished Teaching Award. In addition to his research and university teaching duties, he worked as content reviewer for Houghton-Mifflin for grades 5-6 and as mathematics advisor to Harcourt on grades K-6. More recently, he worked with Engage New York on Grade 6-7 Mathematics and Geometry. He founded the Brigham Young University Summer Math Camp in 2011 with grant from the Dolciani Foundation. He started one of the nation’s first Math Circle Programs at Brigham Young University.

James Farre

A former counselor and assistant faculty member at Epsilon Camp, James Farre is in the process of completing his graduate work in geometric topology at the University of Utah. His research explores the rich interplay between surface theory, three-dimensional hyperbolic geometry, volume, and topological spaces. James is a former dancer who trained in classical ballet and modern dance.

Spencer Bowen

Spencer Bowen is adjunct professor of mathematics and statistics at the University of San Francisco, Director of the San Francisco Math Circle, and an affiliate of the Julia Robinson Math Festival. He has also taught at mathematics programs in summer camps. Mr. Bowen will work with the 7-8 group at Epsilon Camp.

Maria Samuelson, Director of Programs and Admissions

Maria is involved with home school and gifted education groups and her local math club. She has a graduate degree in Theater History and Criticism and has taught university courses in performance art and performance studies. Maria looks forward to working with current and prospective Epsilon Camp families.

Elizabeth Kappler, Volunteer Advisor

Elizabeth Kappler is passionate about math and science education. She has an electrical engineering degree from Rose-Hulman Institute of Technology and is currently a software engineering manager at Intel. She runs several math clubs at her children's school and is heavily involved in education outreach with Intel. She is the parent of a former camper, and enjoys serving the parent community of Epsilon Camp.

Paul Zeitz

Paul Zeitz is Professor of Mathematics at University of San Francisco. He was a member of the first US team to the International Math Olympiad, and coached several US teams. He wrote *The Art and Craft of Problem Solving* in 1999, and produced a 12-hour video course for the Teaching Company in 2009 with the same title. Prof. Zeitz is the co-founder of Proof School in San Francisco, the nation's first full-fledged secondary school for "kids who love math."
