I completed my BSc and MSc in Physics at the prestigious Balseiro Institute, Argentina, with a Fellowship from the Argentine Atomic Energy Commission (2007-2010). In 2011 I was awarded a Fellowship from the Argentine Research Council to pursue a PhD in Physics from the University of Buenos Aires under the supervision of Prof D. Comedi and Prof A. Bragas. I completed my doctorate in 2015 with a focus on the fabrication and manipulation of optical and optoelectronic properties of semiconductor, insulator/semiconductor, and plasmonic/semiconductor nanostructures. For this work, I was later awarded the J. J. Giambiagi Prize for the best PhD thesis in Physics of the year in Argentina.

In September 2015 I joined Prof S. Maier's group at Imperial College London as a Research Associate, where I am a Marie SkÅ‚odowska-Curie Fellow since March 2017. My current scientific interests include the development of low-loss nanostructured dielectric platforms for surface-enhanced spectroscopies and nonlinear nanophotonics, as well as the optical study of 2D materials and their coupling to photonic nanoantennas.
