I am a computational mathematician and part of the Laboratory for Advanced Numerical Simulations (LANS) in the Mathematics and Computer Science Division at Argonne National Laboratory, and a Fellow of the Computation Institute.
I am interested in the development of reliable methods for solving large-scale nonlinear optimization problems and in the implementation and analysis of filter type algorithms. This forms the basis from which I am extending nonlinear optimization methodologies to emerging areas such as mixed-integer nonlinear optimization and optimization problems with complementarity constraints.
