I am currently Ikerbasque Research Associate Professor at the BCMaterials where I lead the 2D Quantum materials lab. My research interests revolve around the behavior of electrons when confined in condensed matter systems and the associated quantum phenomena. I have been particularly interested in the confinement of electrons in one or two dimensions at the interface of so-called topological materials and lately, in the inherent low dimensionality of atomic layers of van der Waals materials and their potential to tailor their properties by proximity in stacked heterostructures.
