Danielle Champney is an associate 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 mathematics. She is also active in cultivating K12 partnerships with Cal Poly, 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 is an associate professor of mathematics at Pacific Lutheran University in Tacoma, Washington and is the editor for the MAA periodical Math Horizons. 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. He has taught at Epsilon from 2018 - 2021, and is enthusiastic about working with future mathematicians of all ages.

Angelina is excited to be returning to Epsilon Camp this summer as a staff member. Although her camper, Nicholas, has aged out, Epsilon was profoundly impactful for him, and she is grateful for the opportunity to continue giving back to the community that helped nurture his passion for mathematics.

Angelina first joined Epsilon in 2022, when Nicholas was in Pythagoras, and this will be her fifth summer, first as a non-parent, at camp. As Camp Operations Manager, she works closely with the staff to ensure camp runs smoothly and looks forward to reconnecting with returning families and welcoming new ones.

Originally from Australia, Angelina holds bachelor’s and master’s degrees in Mechanical Engineering and Business Administration. She serves as SVP and Chief Accounting Officer at Redis and splits her time between the Bay Area, CA and Reno, NV.
