Eva Morrison

Dr. Eva Morrison was a scientist who conducted experiments on nanotechnology and the Vashta Nerada at Synthesis Station. Her primary motivation of her work was to find a means of treating her mother's Alzhiemer's, but she accepted funding from the Time Lords to weaponise her research into the Vashta Nerada for use in the Last Great Time War.

During an inspection of her facility by Cardinal Ollistra, which was 'infiltrated' by the Eighth Doctor, Biotech Dendry accidentally caused a breakdown of the lab's security systems when he attempted to steal samples for himself. Although Doctor Morrison was able to escape to the Doctor's TARDIS with the Doctor, Ollistra, and Roxita, Roxita was devoured by a swarm of Vashta Nerada that had hidden in his gun, and Doctor Morrison was killed when it was revealed that Vashta Nerada had hidden in her suit.
