[1] She is also a Simons Associate at the Abdus Salam International Centre for Theoretical Physics (ICTP).

[6] During and after her PhD, Araujo developed techniques related to Japanese mathematician Shigefumi Mori's proposed theory of rational curves of minimal degree, which she published in 2008.

[6] She was also one of the female mathematicians profiled in the short documentary called Journeys of Women in Mathematics, funded by the Simons Foundation.
