Dean Nora Hill was the Dean of Visualize University. She appeared in the episode His Thoughts Were Red Thoughts, and was the killer of Gabriel Meadows.
She was feeding Gabriel information about Visualize from the inside for articles he was publishing. However, Gabriel started becoming too obsessive about it, and she wanted him to back off. She knew her name was all over the articles, so she brought a hammer and killed him, after which she stole his laptop.
Patrick Jane figures out it was her due to her voting for Bret Stiles , the leader of Visualize, to remain in the leadership position. Rather than voting for someone else, she voted for Stiles, being aware that he was innocent and about to return.
Upon being confronted, she slaps Stiles, stating that she hates him for what he has turned her into.
