I am a senior computational mathematician and part of the (Laboratory for Applied Mathematics, Numerical Software, and Statistics (LANS)) in the Mathematics and Computer Science Division at Argonne National Laboratory, and a Senior Fellow of the Computation Institute.

**Research Statement:**

*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.*
