Sven Leyffer
Deputy Division Director/Senior Computational Mathematician/Argonne Distinguished Fellow
Biography
Sven Leyffer is a Deputy Division Director and senior Computational Mathematician in the Mathematics and Computer Science Division at Argonne which he joined in 2002. Sven is a SIAM Fellow, a senior fellow of the University of Chicago/Argonne Computation Institute, and an Argonne Distinguished Fellow.
He was SIAM President from 2022-2024 and serves on the editorial board of Computational Optimization and Applications.
In 2006, Leyffer (along with two colleagues) received the Lagrange Prize in Continuous Optimization, which is awarded only once every 3 years. In 2016, he received the Farkas Prize from the INFORMS Optimization Society.
Leyffer obtained his Ph.D. in 1994 from the University of Dundee, Scotland, and held postdoctoral research positions at Dundee, Argonne, and Northwestern University.
Research Interests
- Development of efficient and reliable methods for solving large-scale nonlinear optimization problems.
- Applications of nonlinear and discrete optimization.
- Extending nonlinear optimization methodologies to emerging areas such as mixed-integer nonlinear optimization, optimization problems with PDE constraints, and optimization problems with complementarity constraints
