He wrote problems for MATHCOUNTS and still enjoys contests like the MoMath Masters competition and the World Sudoku Championships. He holds an MS in math from Stanford University and in astronomy from UC Berkeley.

Edward Seidel is the President of the University of Wyoming and a leading academic on Einsteinian physics and high-performance computing. He serves on the U.S. Department of Energy’s Advanced Scientific Computing Advisory Committee and a Commissioner for the U.S. Council on Competitiveness. He has previously served as Vice President of Research and Innovation at University of Illinois and Director of the National Center for Supercomputing Applications. His career includes senior leadership roles at distinguished institutions from the Max Planck Institute for Gravitational Physics to the National Science Foundation.

Wendy Tam is Professor of Political Science, Computer Science, Law, and Biomedical Informatics at Vanderbilt University, an affiliate at the National Center for Supercomputing Applications and Professor Emerita at the University of Illinois at Urbana-Champaign, and Professional Researcher in the School of Medicine at the University of California at San Francisco. Mathematics is the tie that holds together her eclectic interests. She has loved math all her life, but really discovered its beauty when she started teaching math to her sons, who love math even more than she does! Her sons wanted to do math with other kids, so she began her own math circle and started teaching at math summer camps, most notably part of the founding faculty of Campersand. Her mathematical journey has been immensely fulfilling and has taught her that sharing mathematical beauty (especially with children) is the surest and quickest way to multiply its appreciation and joy.

Beth Malmskog is an Associate Professor in the Department of Mathematics and Computer Science at Colorado College.
