Biographical Review

I am an Assistant Professor (Profesor Ayudante Doctor) at the Universidad Autónoma de Madrid, from September 2017. Previously, I was a Marie Sklodowska-Curie Individual Fellow at the Instituto de Ciencias Matemáticas (ICMAT) in Madrid (2015-2017), and had postdoctoral appointments at the Nigel Hitchin Laboratory of ICMAT (2014-2015), the École Polytechnique Federal de Lausanne (2013-2014), and the Centre for Quantum Geometry of Moduli Spaces (Aarhus, 2010-2012). I have also held visiting positions at the Max Planck Institute for Mathematics (Bonn), at the Humboldt University (Berlin), and at the Hausdorff Research Institute for Mathematics (Bonn). I obtained my PhD in 2009 at the Universidad Autónoma de Madrid.

Research Interests

My research is in the areas of differential geometry and algebraic geometry, and has strong links with geometric analysis and mathematical physics. The main projects I have carried out include special metrics and connections in Kähler geometry (constant scalar curvature Kähler, Hermite-Yang-Mills, vortices, Hitchin equations) and their relation to stability conditions in algebraic geometry (GIT), moduli spaces (bundles and varieties, Higgs bundles, wall-crossing in DT-Theory), special holonomy and mirror symmetry (Calabi-Yau, G2 geometry, Hull-Strominger system, spin geometry, generalized geometry, T-duality).

My current main research interests are complex non-Kähler geometry, special holonomy with torsion, and vertex algebras. In my work I transfer techniques from Kähler geometry to address problems in complex non-Kähler geometry, using the theory of Courant algebroids and other objects reminiscent from higher gauge theory. My research builds towards providing mathematical underpinnings for the interesting phenomenon of (0,2)-mirror symmetry, using special holonomy with torsion and the theory of vertex algebras. In particular, in the last 8 years I have extensively studied the Hull-Strominger system of partial differential equations, which provides a common ground for these three topics.
