From events held in U.S., Canada, Latin America, Europe, Africa, Asia, or Australia, our annual symposia are among the most anticipated events of the year. Plenary talks, tutorials, workshops and the collaborator showcase create opportunties to share research, learn from each other, and collaborate on future opportunities.
These events also allow our global community an opportunity to connect face-to-face. Whether it is to share scientific breakthroughs, build massive Lego sets or dance on stage together, each symposium brings our community together and sets new paths for collaboration.
The 2026 Global Symposium takes place Oct. 20-22 in New Brunswick, N.J. Registration is open.
The 2026 APAC Symposium takes place Nov. 13-15 in Yonsei, Korea. Registration is open.
The 2026 Canada Symposium takes place Nov. 17-18 in Toronto, Ont. Registration is open.
The 2026 India Symposium has been scheduled for Dec. 11 in Chennai. More details and registration information to come.
