BIMSA Math Circle I (2025-2026)
For Students Ages 12–18 Who Want to Explore Olympiad Mathematics
Do you enjoy solving puzzles, challenging yourself, and thinking outside the box?
At the BIMSA Math Circle, you’ll dive into the world of Math Olympiad–style problem solving—a world of creativity, logic, and discovery!
🔹 What is the BIMSA Math Circle?
A weekly program designed to:
Introduce students to the beauty of Olympiad mathematics
Explore problem-solving in number theory, combinatorics, geometry, and algebra
Practice with problems inspired by AMC, AIME, and IMO competitions
Develop creative approaches rather than memorizing formulas
🔹 Who can join?
Students ages 12–18 (grades 7–11)
Enthusiastic learners at any level—no prior competition experience needed!
🔹 What will we do?
Solve challenging math problems in a fun and collaborative setting
Learn strategies used by successful Olympiad participants
Work in small groups, guided by experienced instructors
🔹 Why join?
Build powerful problem-solving and logical reasoning skills
Experience the excitement of Olympiad mathematics
Prepare for contests—or just enjoy the adventure of deep mathematics
Become part of a community that loves to learn and challenge themselves

Lecturer Intro
Cezar Lupu obtained his PhD degree from the University of Pittsburgh in 2018 with a thesis on special values of Riemann zeta and multiple zeta functions under the supervision of Piotr Hajlasz and William C. Troy. Between 2018-2021, he was a postdoctoral scholar at Texas Tech University under the mentorship of Razvan Gelca and Dermot McCarthy. In 2021, he moved to China as a postdoctoral fellow at the Beijing Institute of Mathematical Sciences and Applications (BIMSA) and Tsinghua University under the mentorship of Shing-Tung Yau until 2024. His main research interests are in the areas of number theory, analysis and special functions. Most of his recent research is centered around special values of L-functions and multiple zeta functions which play an important role at the interface of analysis, number theory, geometry and physics. He taught numerous courses at Pitt and TTU both undergraduate and graduate ranging from calculus and linear algebra to abstract algebra and real analysis. Also, he coached the best undergraduate students for the William Lowell Putnam Mathematical Competition. After moving to China, he taught courses at the Qiuzhen College, Tsinghua University. Together with other colleagues from Tsinghua University, he is organizing the Shadow Putnam Mathematical Competition at the Qiuzhen College. Moreover, starting 2023, he is the academic director of the International Mathematics Summer Camp (IMSC).
