She was a graduate of Starfleet Academy and became a noted and well-respected physicist in the Federation. In the early 2350s, she worked at the Vulcan Science Academy, and in 2353 she had a son with Robert Ba'dos, named Jaden.
However, in 2354, a warp funnel experiment lost containment and killed both Ba'dos and Yamashiro, leaving Jaden orphaned. Si'tann, a friend of Ba'dos, adopted Jaden as his ward, naming him Sovok. (TNG video game: Hidden Evil)
