Hernán grew up in Argentina, where he pursued studies in Industrial (UTN, 2 years) and Nuclear Engineering (Instituto Balseiro, MSc equivalent, 2010). After gaining experience in the field of Computational Fluid Dynamics as a Research Engineer at the National Atomic Energy Commission, he moved to France where he completed a MSc in Fusion Science (2012), at the Aix-Marseille University, with a Master dissertation carried out at ITER (the International Thermonuclear Experimental Reactor), focusing on superconducting magnet cooling. His interest for the cooling of cryogenic systems led him to completing a PhD in experimental cryogenic heat transfer at the University of Paris-Saclay (Boiling Helium Natural Circulation Loops in Transient Regime, 2015). In 2016, he received a MCSA COFUND CERN fellowship, with which he carried out a 3-year research project at CERN, at the Superconducting Radiofrequency and Cryogenics Central Laboratory sections. He led the development of superconducting ultra fine thermometry below 2 K based on Au-Sn transition edge sensors. This was his first contact with the microtechnology world and with EPFL, through the CMi. In 2019, following this new passion for the microworld, he joined Prof. Niels Quack's group as a PostDoc in Integrated Photonics and MEMS. In 2020, Hernán received an SNSF Ambizione grant, in collaboration with Prof. Jürgen Brugger and Dr. Giovanni Boero, from the LMIS1, to work on superconducting microresonators for microwave sensing, a project combining his expertise in low temperature physics, nanotechnology and waves. The project started in 2021 and will extend until 2025. He continues to collaborate with Prof. Quack in Integrated Photonics topics and teaching in the Photonic Micro- and Nanosystems course.
