The Southeast Center for Mathematics and Biology (SCMB) will host its 3rd Annual Symposium as a free online event from December 7th-10th, from 12:00pm-2:00pm (EST). The Symposium will explore the theme of Interactional Expertise—the secret sauce behind many successful cross-disciplinary collaborations. The event will host panel discussions with math-bio researchers and explore the successes and the pitfalls of collaborating across disciplines. Junior speakers from all 4 NSF-Simons MathBioSys research centers will contribute talks demonstrating the innovative work being done at the math-bio interface. The Symposium will conclude with a plenary talk from Heather Harrington (Oxford) on Algebraic Systems Biology and a poster session open to all registrants.
