T'Viss was a Vulcan professor, and one of the Federation's leading temporal physicists throughout the late 23rd century and most of the 24th century.


In the 2260s, T'Viss served as the primary scientific advisor to Antonio Delgado, Starfleet's leading proponent of time travel research, and as a research fellow at Cambridge University. Following the creation of the Department of Temporal Investigations, T'Viss moved to work with that department. (DTI novel: Forgotten History)

T'Viss continued working with the DTI into the 2380s and taught classes to new agents at the department, though T'Viss was known to dumb down her lectures. (DTI novel: Watching the Clock)
