Sven Leyffer's Bio
Born in Hamburg, Germany, Sven obtained his Ph.D. in 1994 from the University of Dundee, working on mixed-integer nonlinear programming problems with Roger Fletcher. He has held postdoc positions at Dundee, Northwestern, and Argonne, where he now works as a Senior Computational Mathematician in the Mathematics and Computer Science Division. Sven is a Senior Fellow of the Computation Institute at the University of Chicago.
Sven was a co-editor of Mathematical Programming and served as an editor-in-chief of Mathematical Methods of Operations Research. He serves on the editorial board of Computational Optimization and Applications and Mathematics of Computation. In addition, Sven has served as the INFORMS Optimization Vice-Chair for nonlinear programming and as the Program Director of the SIAM activity group on optimization. Sven was SIAM Vice President for Programs from 2010-2013. Currently, Sven served as the Secretary of ICIAM from 2015 to 2022. He is the current SIAM President. For other appointments, see this list of other appointments.
Together with Roger Fletcher and Philippe L. Toint, Sven was awarded the Lagrange prize in optimization in 2006. In 2009, Sven became a SIAM Fellow. In 2013, Sven won the 2012 COAP Best Paper Prize with Chungen Chen and Roger Fletcher for their paper on nonmonotone filter methods. In 2016, Sven was awarded the Farkas Prize for Mid-career Researchers by INFORMS.

Sven's dad, Werner Leyffer, runs the smallest Seafarer's Mission in Glueckstadt, Germany, featured in these articles of the Norddeutsche Rundschau from 2012, 2013, 2014, and 2015. Some old personal stuff about Gwen & Sven Leyffer, and here is a Scottish Country dance that Sven devised, called The Teddybears' Picnic (which we first performed in Teddybear costumes).
