Dr. Juliana Jaramillo Fernandez is a Marie Sklodowska-Curie COFUND -PSPHERE-postdoctoral researcher at the Catalan Institute of Nanoscience and Nanotechnology, Barcelona, Spain. She obtained her PhD from CENTRALESUPÉLEC in 2015 (one of the top five Universities in France - QS ranking 2020) with a thesis on Thermal Nanoscience, entitled " Tuning thermal conductivity of AlN films by strain, structural inhomogeneity and interfacial oxidation". She obtained her M.Sc in Materials Science at Université de Limoges in 2011. She is using her expertise on micro and nanoscale heat transfer to develop sustainable thermal management solutions that can significantly reduce the current high energy footprint of modern thermoregulation technologies. She is developing new passive systems that only make use of non-toxic materials, while developing further understanding on thermal energy transport via surface phonon polaritons. She is also interested at heat transfer in semiconductor nanostructures, tailoring physical properties of low-dimensional materials, controlling thermal transport within nanostructures and across interfaces and grain boundaries. She is also interested in phonon engineering, thin film growth and thermal characterization
