Sven Leyffer

Project Leader/Sr. Computational Mathematician

Biography

Sven Leyffer joined the Mathematics and Computer Science Division at Argonne in 2002, where he is now a senior computational mathematician. Sven is a SIAM Fellow, and a senior fellow of the University of Chicago/Argonne Computation Institute.

He is the current ICIAM Secretary and serves on the editorial boards of Computational Optimization and Applications, and Mathematics of Computation; he also is editor-in-chief of Mathematical Programming B.

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 reliable methods for solving large-scale nonlinear optimization problems
  • Implementation and analysis of filter-type algorithms
  • Extending nonlinear optimization methodologies to emerging areas such as mixed-integer nonlinear optimization and optimization problems with complementarity constraints
