Hannah Vermeulen is a Belgian scientist and pioneer of the modern VX movement.

She was active and publishing until mid-2010, at which point she became secretive about her work. Her current location or employment isn't known. She is still listed as an adjunct professor at the University of Brussels, but not against any faculty.

When referred to at Gottingen 09 as "The new Yalgeth" she is supposed to have quipped "Mais, je n'ai pas son courbes" ("but I don't have her curves") which appears to be a reference to her waif-like appearance but is of course a reference to the Yalgeth Vectors, the "lost" set of equations which according to some, contradict not only Connery, but invert entirely the field of VX superpositionality.
