Argonne National Laboratory

Sven Leyffer is an internationally recognized leader in numerical optimization, with major accomplishments in three distinct hot-topic areas: nonlinearly constrained optimization, mixed-integer nonlinear optimization, and optimization problems with equilibrium constraints. In all three areas, he has made fundamental contributions to the theoretical foundations; developed state-of-the-art methods and robust implementations; and promoted novel applications, many of pivotal importance to the DOE.
