Colloquium Series

Exposure to New Ideas
Get Inspired
Forge Connections with Experts

Welcome to The Department of Mathematics and Statistics Colloquium Series, where curiosity, rigor, and innovation intersect.

Each semester, this series brings together leading researchers, visiting scholars, faculty, and students to examine cutting-edge work in mathematics and statistics. Talks span theory, computation, modeling, data analysis, and applications that address real-world challenges across science, policy, industry, and beyond.

If you join us, you’ll gain exposure to new ideas, forge connections with experts, and expand your intellectual horizon. Whether you’re building a research agenda, refining your thesis topic, or simply looking for new inspiration, the Colloquium provides a stage for discovery, collaboration, and growth.
