She was a Fellow of the American Physical Society (APS)[1] and of the Institute of Electrical and Electronics Engineers (IEEE).
Van Vliet then obtained an MA in physics from the same university in 1953, and a PhD in 1956 for a thesis titled Current Fluctuations in Semiconductors and Photoconductors, under Gerardus J.
[6] Van Vliet was a teaching assistant (1949–1953) at the Vrije Universiteit in Amsterdam, and then a NV Philips Research Fellow (1953–1956) at the same university.
This was followed by an appointment as a Fulbright Fellow in the electrical engineering department at the University of Minnesota (1956–1957), where she rose to assistant professor.
She published over 200 scientific publications and several books included a graduate textbook, "Equilibrium and Non-Equilibrium Statistical Mechanics".
