Marta Bunge (1938-2022) was an Argentinian-Canadian mathematician. Her research included fibered categories, stacks (with values in categories, hence 2-sheaves) and groupoids, topos theory, geometric Galois theory of covering spaces, synthetic differential topology, amongst others.
On internal presheaves in elementary toposes:
On category-valued stacks (2-sheaves) as internal categories in a sheaf topos, and on weak equivalences of internal categories:

Marta Bunge reported at the category conference in Calais in June 2008 about her joint work with Claudio Hermida about some aspects of Diaconescu-type results in categorical dimension 2. Her slides from Calais can be found here. There are also some conjectural statements about higher n, with an interesting definition when an n-functor between strict n-categories should be called a fibered n-category.
