T'Viss was a Vulcan Professor, and one of the Federation's leading temporal physicists through most of the 24th century.

Understanding temporal mechanics better than most others, she was disinclined to dumb her lectures on the subject down for her students. She worked with the Department of Temporal Investigations upon it's founding in 2270, and would work closely with the organization for over a century. (ST novel: DTI: Watching the Clock)
