[6] During her PhD, Ramagge won the 1993 B. H. Neumann Prize for the most outstanding talk presented by a student at the Annual Meeting of the AustMS.
[6] During this time, she supported the establishment of the Sydney Mathematical Research Institute, working with Professor Geordie Williamson and Professor Anthony Henderson to raise $6.5 million of philanthropic donations from the Simon Marais Foundation, the Hooper Shaw Foundation and individuals to found the institute.
[9][11][12] Ramagge returned to the United Kingdom to take up a leadership position at Durham University as Executive Dean (Science).
Her current major projects focus on the general structure theory of totally disconnected, locally compact groups; and operator algebras.
[6] In the field of totally disconnected, locally compact groups, Ramagge is driving the development of the geometric aspects of the theory.
In operator algebras, she works mainly on C*-algebras, which were introduced to provide mathematical models for quantum mechanics, and in classifying their equilibrium states.
