Personal profile


Research on linear algebra, operator theory and systems and control theory.

Several current project are concerned with linear algebra in spaces with an indefinite inner product.


Teaching: Mathematical control and systems theory, linear algebra, and although it is not my expertise, I am teaching an Introduction to Financial Mathematics course.
