About Me
About Me
I am a postdoctoral researcher at the Departament de Matemàtiques i Informàtica, Universitat de Barcelona in Spain. Before, I was a postdoctoral researcher at ETH Zurich, where I completed my PhD studies in 2023.
Research interests: Partial differential equations; nonlocal operators; harmonic & microlocal analysis; calculus of variations; inverse problems & imaging.
