Scientific Activity
Most of the research activity concerns the development and the analysis of numerical methods for large scale systems, parallel computing, nonlinear optimization and related applications. In particular theoretical and computational results have been obtained about the Inexact Newton interior point method for nonlinear programming problems and nonlinear systems, including the analysis of different iterative solvers for inner linear symmetric indefinite systems. Non monotone strategies are analyzed also for the semi-smooth case, with application to optimal control problems and variational inequalities. More recent research interests are in non smooth convex optimization methods for inverse problems in image reconstruction and stochastic optimization methods in machine learning. Contributions are obtained on first-order forward-backward and primal-dual metric methods and on step selection rules for stochastic algorithms. The results of her research activity are described in about 60 publications in international scientific journals, proceedings and books, in several software packages and in a number of communications to conferences.
As coordinator of research projects, she organized meetings and workshops on mathematical software, parallel computing and numerical optimization. From 2008 she is member of the Italian research group OASIS (http://www.oasis.unimore.it/site/home.html).
