She has also extensive work in the development of algorithms for nonconvex minimization. Her PhD thesis introduced and analyzed solution methods for variational inequalities, the latter being a generalization of the convex constrained optimization problem. She recently co-authored the Springer book "Set-Valued Analysis and Monotone Mappings". Regina is an associate editor of several journals from the area of optimization, including SIAM Journal on Optimization, Applied Mathematics and Computations, Communications in Mathematical Analysis, TOP, and the Australian and New Zealand Journal for Industrial Mathematics. Regina enjoys learning, teaching, supervising and collaborating with others. Her main and only reason for doing math is pleasure.
