My research aims to probe experimentally the physics emerging in novel materials as result of the strong correlations between electrons. In particular, my current interest focuses to understand the electronic structure of iron superconductors, metallic systems on magnetically frustrated lattices and topological superconductors by using quantum oscillations. Quantum oscillations probe directly the Fermi surface of metallic systems or novel superconductors in their normal state. These studies provide direct access to the electronic states which are the basis of developing novel theories and help to the development of novel materials with improved properties. I use a variety of sensitive experimental techniques in high magnetic fields and low temperatures to probe new phases of matter in micron size crystalline materials. My research benefits from access to the highest magnetic fields available in the world and strong international collaboration with material scientists, chemists and theoreticians.
