Biography

Hi, I’m Fernando, currently a postdoctoral researcher at the Donostia International Physics Center. I obtained my Phd in theoretical condensed matter physics from the Theory of Quantum Materials and Solid State Quantum Technologies department at the Material Science Institute of Madrid (CSIC). My interests include: topological matter, correlated electrons, Majorana physics, and moiré systems. My research activity is at the frontier between fundamental physics and its technological applications.

I’m passionate about scientific computation, numerical techniques (Quantum Transport, Tight Binding, DMRG, TNs…), and open-source development mostly in Julia (see my Github page).
