I am a mathematician working on Classical Analysis and Special Functions. Since March 2015 I am a FCT Postdoctoral Fellow in the Centre for Mathematics at University of Coimbra and faculty member of the PhD Program in Mathematics of the Universities of Coimbra and Porto.
Some of my recent papers are listed below (for a full list of publications see MathSciNet).  On semiclassical orthogonal polynomials via polynomial mappings II: Sieved ultraspherical polynomials revisited (with M. N. de Jesus and J. Petronilho). Preprint  On monotonicity of zeros of paraorthogonal polynomials on the unit circle. Preprint  Refined interlacing properties for zeros of paraorthogonal polynomials on the unit circle (with J.
