Biography

I am an Assistant Professor in the Department of Mathematical Analysis at the University of Valencia. I teach a variety of courses in mathematical analysis and calculus across several degree programs. My research focuses on functional analysis, especially the geometry of Banach spaces. My interests include, among others, the theory of norm-attaining and numerical-radius-attaining operators and Bishop–Phelps–Bollobás-type properties; other types of norm-attaining mappings (Lipschitz, multilinear, polynomials, tensors, etc.); diameter 2 properties in Banach spaces; and Lipschitz-free spaces.
