Pol Lloveras is associate professor at the Group of Characterization of Materials of the Department of Physics of the Universitat Politècnica de Catalunya (Catalonia, Spain). He devoted his PhD (Universitat de Barcelona, Spain, 2010) to the theoretical study and modeling of structural and thermodynamic properties of ferroelastic and magnetoelastic systems, including the elastocaloric effect. After a first post-doctoral stage at the École Polytechnique (Palaiseau, France), he joined his current Group in 2012. Since then, he has specialized in the analysis of barocaloric effects in the solid state for environmentally friendly cooling methods. His studies involve high-pressure techniques such as calorimetry, dilatometry and diffraction, the latter performed in a number of short stages in Large Scale Facilities. Over the last years, thanks to collaborations with other Groups worldwide, he has been investigating the BCE of a vast range of materials including metallic alloys, ferroelectrics, hybrid perovskites, metalorganic frameworks, organic compounds and spin-crossover complexes. It is worth mentioning the identification of colossal barocaloric effects close to those in current harmful fluids, unveiled in a number of plastic crystals and other compounds. As for teaching duties, he is or has been in charge of subjects on thermodynamics, electromagnetism, solid-state physics and physics of materials, both at the undergraduate and master level.
