Members of the public are invited to attend the keynote address by Theresa MacPhail, PhD, Assistant Professor Science and Technology Studies at Stevens Institute of Technology, and author of The Viral Network: A Pathography of the H1N1 Influenza Pandemic (Cornell University Press, 2014). Dr. MacPhail will speak on “The Evolution of Viral Networks: H1N1, Ebola, and Zika” describing the culture of public health, the production of scientific knowledge, networks of expertise, information sharing, and everyday experiences of epidemiologists, microbiologists, biomedical scientists, and medical practitioners. Dr. MacPhail’s address will take place on Monday, January 29, in the Balcony B Auditorium of National Institutes of Health (NIH) Natcher Conference Center, located on the Bethesda, Maryland, campus of NIH, and it will be part of the NLM History of Medicine Division’s 2018 lecture series, which promotes awareness and use of NLM and other historical collections for research, education, and public service in biomedicine, the social sciences, and the humanities.
