I am a Professor of Mathematics and my research focuses on several aspects of optimization, ranging from functional analysis and variational inequalities to practical applications. I publish in optimization theory, solution techniques for nonsmooth optimization, and convergence analysis of algorithms. My interests span 

theoretical aspects of optimization,
constraint qualifications for nonsmooth optimization,
theory of monotone operators,
convex analysis,
multiobjective optimization and the development of new scalarization techniques.

I have published more than 80 journal articles, several book chapters, and edited many special volumes and special issues for international journals. I co-authored a Springer book entitled "Set-valued Analysis and enlargements of monotone operators", which focuses on the use of point-to-set theory for optimization.
