These include Dirichlet series for matrix products, mean-field approximations in opinion dynamics, graph sequence grammars, anti-mixing methods for iterated learning, and tools for renormalizing network-based dynamical systems. The talk will be self-contained and non-technical.</span></span></span></span></div><div style="font-family: 'Segoe UI',Helvetica,Arial,sans-serif; font-size: medium; margin: 0px;" data-mce-style="font-family: 'Segoe UI',Helvetica,Arial,sans-serif; font-size: medium; margin: 0px;"><span data-mce-style="font-family: Calibri,sans-serif; font-size: small;" style="font-family: Calibri,sans-serif; font-size: small;" size="2" face="Calibri,sans-serif"><span style="font-size: 11pt;" data-mce-style="font-size: 11pt;"><span data-mce-style="color: black; font-family: Tahoma,sans-serif; font-size: medium;" style="color: black; font-family: Tahoma,sans-serif; font-size: medium;" size="3" color="black" face="Tahoma,sans-serif"><span style="font-size: 12pt;" data-mce-style="font-size: 12pt;"><br> </span></span><span data-mce-style="color: black; font-family: Tahoma,sans-serif; font-size: medium;" style="color: black; font-family: Tahoma,sans-serif; font-size: medium;" size="3" color="black" face="Tahoma,sans-serif"><span style="font-size: 12pt;" data-mce-style="font-size: 12pt;"><b>Bio:</b></span></span></span></span></div><div style="font-family: 'Segoe UI',Helvetica,Arial,sans-serif; font-size: medium; margin: 0px;" data-mce-style="font-family: 'Segoe UI',Helvetica,Arial,sans-serif; font-size: medium; margin: 0px;"><span data-mce-style="font-family: Calibri,sans-serif; font-size: small;" style="font-family: Calibri,sans-serif; font-size: small;" size="2" face="Calibri,sans-serif"><span style="font-size: 11pt;" data-mce-style="font-size: 11pt;"><span data-mce-style="color: #333333; font-family: Tahoma,sans-serif; font-size: medium;" style="color: #333333; font-family: Tahoma,sans-serif; font-size: medium;" size="3" color="#333333" face="Tahoma,sans-serif"><span style="font-size: 12pt; background-color: white;" data-mce-style="font-size: 12pt; background-color: white;">Bernard Chazelle is Eugene Higgins Professor of Computer Science at Princeton University, where he has been on the faculty since 1986. His current research focuses on the “algorithmic nature” of living systems. A professor at the Collège de France in Paris in recent years as well as a member of the Institute for Advanced Study in Princeton, he received his PhD in computer science from Yale University in 1980. The author of the book, "The Discrepancy Method," he is a fellow of the American Academy of Arts and Sciences, the European Academy of Sciences, the Association for Computing Machinery, and the recipients of three Best-Paper awards from SIAM.</span></span></span></span></div><div style="font-family: 'Segoe UI',Helvetica,Arial,sans-serif;
