Patricia Flatley Brennan, RN, PhD, is the Director of the National Library of Medicine (NLM), one of the 27 Institutes and Centers of the National Institutes of Health (NIH). Since assuming the directorship in August 2016, Dr. Brennan has positioned the Library to be the hub of data science at NIH and a national and international leader in the field. She spearheaded the development of a new strategic plan that envisions NLM a platform for biomedical discovery and data-powered health. Leveraging NLM’s heavily used data and information resources, intramural research, and extramural research and training programs, Brennan aims for NLM to accelerate data driven discovery and health, engage with new users in new ways, and develop the workforce for a data-driven future.
