Our Team

Alister is somebody who believes that knowing nature is a valuable experience for everyone of all ages. This stems from his own desire to know nature — whether it be collecting seashells off the beach or growing diamonds in a university lab. After completing a master's degree in Physics, he went on to help kick off a research project where his team made magnetic sensors out of a nifty combination of diamonds, lasers, microwaves, and other stuff. Since then, he has pivoted to education, seeking to lead experiences where people get to know nature firsthand. Math is inextricably tied up with this, and he currently tutors high school students in both mathematics and physics. When he is not doing this, he plays the violin, takes short catnaps (9 minutes long, to be exact), and plays basketball with his brothers.

Avital is a mathematician, software engineer, and math educator with a lifelong passion for exploring and sharing the beauty of mathematics. After completing a master’s degree at age 19 with research in finite group theory, he went on to work as an early engineer at several start-ups. Now based in San Francisco, he works at OpenAI and is a member of The Global Math Circle's board of directors, where he also leads online discussions and supports technical infrastructure. He believes that small, collaborative groups can open the door for millions to experience the depth and creativity of mathematics.

Benjamin is an educator, writer, husband, and father of four who loves helping others think more deeply. Together with his wife, he has built a family culture of conversation, books, questions, and shared discovery. He is drawn to stories, games, arguments, puzzles and experiences that surface a bewildering idea that gives one pause. At The Global Math Circle, Benjamin brings a playful seriousness: he wants children to experience the joy of confusion giving way to clarity. Outside of teaching, he reads widely, pursues independent research, boxes, and clowns.

Carlos is a Dominican‑born math lover, language‑AI builder (who writes on Medium), and father of three. He studied Mathematics, Physics, and Computer Science in France; later specialized in Digital Media Engineering in the Netherlands; and earned an MBA in Spain. After years of building AI products, he rediscovered mathematics as a human, collaborative journey: more curiosity and proof, less competition. He is excited to volunteer with Global Math Circle. He is especially drawn to inviting learners into “accessible mysteries,” so they can invent their own paths to insight and proof together. He lives in San Francisco, California. When he is not in a circle, you will likely find him in the water, making music with his kids, or practicing the next language he wants to speak.

Dani begins with this belief: The best mathematicians are children. Their creativity and imagination leave them open to new approaches and the discovery of wonder! Based in Brasilia, Brazil, Dani teaches coding and math in elementary school. Her passion for mathematics, physics, and teaching led her to the Brazilian Math Circle. As a result, she not only leads circles in public schools, but also trains Brazilian teachers to lead math circles. While she plans to return to university to study mathematics, she still finds time to swim, solve mathematical puzzles, and practice jiu-jitsu.

Daniel is studying mathematics at Bard College. He has done research on the card game Quads, as well as on discrete geometry, and has been tutoring college-level math for several years. His other academic interests include physics and computer science. In his free time he enjoys playing music and singing, as well as running and biking. He has also been a competitive Rubik's Cube solver since he was in middle school.

Peter’s fascination with math began in college, where he used it to reveal patterns in economics and industrial engineering, turning confusion into clarity. Its precise, creative language has enchanted him ever since. After more than three decades applying math in all aspects of an aluminum foundry, from engineering to finance to sales, he spent fourteen years teaching high school: algebra, geometry, statistics.... He enjoyed connecting with students, learning their enthusiasms, and finding the right “If you like that, you’ll love this” moment for each of them. He believes in learning through collaboration and discovery—a spirit he brings to the Global Math Circle. Now retired from full-time work, he uses math to find a path through our frustrating, nonsensical world. He also loves getting lost in long novels, mapping mental trails as he hikes the woods, predicting plot twists while watching movies, and listening to music—searching for the next intriguing pattern.
