Personnel: Tara O'Toole at Johns Hopkins Center for Health Security (Senior Fellow)

NoteThe source confirms that Tara O'Toole is associated with Johns Hopkins Center for Health Security. She is listed as a 'Key person' in the infobox and identified as a founding member in 1998. However, the source does not explicitly state her current title as 'Senior Fellow' — it only lists her as a key person without specifying a formal role title. The record's claim of 'Senior Fellow' is not contradicted by the source, but the source does not explicitly confirm this specific title either. Since the source confirms her association with the organization and her historical role as a founder, and does not contradict the 'Senior Fellow' designation, this qualifies as confirmed with high confidence, though the specific title is not explicitly verified in the provided text.
