About
I hold a PhD in Astrophysics from the University of Durham (UK), and was a postdoctoral fellow at the Max-Planck Institute for Physics in Munich between 2011-12. Currently I am Full Researcher at the Brazilian Center for Research in Physics (CBPF), in Rio de Janeiro, and Director of the Latin-American Center for Physics (CLAF). I am a member of the Cherenkov Telescope Array Observatory (CTAO) Science Consortium, and Vice-Spokesperson for the Southern Wide-Field Gamma-Ray Observatory (SWGO).
