Research Interests
 My research interests lie in the field of Functional Analysis. In particular, a have been doing research in the following areas:
  • Banach spaces;
  • Operators on Banach and Hilbert spaces and algebras of such operators;
  • Banach lattices;
  • Positive operators on Banach lattices and collections of such operators;
  • Nonnegative matrices and semigroups of such matrices.
