    My research centers in a mix of Algebraic Geometry, Differential Geometry and Algebraic Topology and their relationships with the equations of Mathematical Physics. More precisely, I am interested in the study of the geometry and topology of moduli spaces of (mainly Higgs-) bundles over curves. My arXiv personal area can be reached from here:

    Topics on current projects:

    • Study of connected components of the moduli space Higgs bundles for the groups SO(p,q)
    • Relate the existence of exotic connected components of these moduli spaces with positivity property of the corresponding real Lie group.
    • Study of branes in the moduli space of Higgs bundles arising from fixed points by tensorisation by finite-order line bundles.
    • Study the normality of Higgs bundle moduli.
    • Study of the moduli space of the so-called skew-symmetric pairs.
