Research Activities 

My research activities mainly ocuses on in global, continuous, non linear optimization problems.
I am currently contributing to gol++, a library designed to allow the programmer to quickly design and implement of solvers for continuous optimization problems, or tune existing general purpose solvers to any particular problem.
I wrote an implementation of the Barziliai-Borwein gradient method which uses filters to speed up the convergence. You can find it in the gol++ library.

My current research activities involve spacecraft trajectory optimization and portfolio selection problems.

I am also interested in using operational research techniques to solve molecular conformation problems, and minimization of atomic cluster potentials though deterministic optimization.
