In all illustrations presented\, I will try to point out connections be tween the “traditional” numerical analysis we know and love\, and  the more modern data-driven tools and techniques we now have – and s ome mathematical questions they hopefully make possible for us to answer.P art I will focus on results from the early 1990s (the last "AI winter") th at are now being resurrected and extended. BioYannis Kevrekidis studied C hemical Engineering at the National Technical University in Athens. He the n followed the steps of many alumni of that department to the University o f Minnesota\, where he studied with Rutherford Aris and Lanny Schmidt (a s well as Don Aronson and Dick McGehee in Math). He was a Director's Fel low at the Center for Nonlinear Studies in Los Alamos in 1985-86 (when Sov iets still existed and research funds were plentiful). He then had the g ood fortune of joining the faculty at Princeton\, where he taught Chemical Engineering and also Applied and Computational Mathematics for 31 yea rs\; eight years ago he became Emeritus and started fresh at Johns Hopki ns (where he somehow is also Professor of Urology). His work always had to do with nonlinear dynamics (from instabilities and bifurcation algorith ms to spatiotemporal patterns to data science in the 90s\, nonlinear ident ification\, multiscale modeling\, and back to data science/ML)\; and h e had the additional good fortune to work with several truly talented expe rimentalists\, like G. Ertl's group in Berlin. Currently -on leave from Ho pkins- he works with the Defense Sciences Office at DARPA. When young an d promising he was a Packard Fellow\, a Presidential Young Investigator  and the Ulam Scholar at Los Alamos National Laboratory. He holds the Colb urn\, CAST\,  Wilhelm and Walker awards of the AIChE\, the Crawford an d the Reid prizes of SIAM\, he is a member of the NAE\, the American Acade my of Arts and Sciences\, and the Academy of Athens.  LOCATION:LGRT 201 and via Zoom (email Marie for a link\, wallace@ecs.umass .edu) END:VEVENT END:VCALENDAR
