James Colgrove is a Professor of Sociomedical Sciences at the Columbia University Mailman School of Public Health.

Dr. Colgrove's most recent book is Epidemic City: The Politics of Public Health in New York.

He is also the author of State of Immunity: The Politics of Vaccination in Twentieth-Century America; co-author, with Amy Fairchild and Ronald Bayer, of Searching Eyes: Privacy, the State, and Disease Surveillance in America; and co-editor of The Contested Boundaries of American Public Health.


Robert Klitzman is a Research Scientist and Investigator with the HIV Center's Development Core. He co-founded the Columbia University Center for Bioethics, and is the Director of the Masters of Bioethics Program at Columbia. He is a Professor of Clinical Psychiatry at Columbia University, and a member of the Division of Psychiatry, Law and Ethics in the Department of Psychiatry.

His book, Being Positive: The Lives of Men and Women With HIV, examines the meanings of HIV infection, the ways in which individuals living with HIV find sources of hope in their lives, and the ways the virus alters individuals' identities and social and moral worlds. He has conducted research with Ronald Bayer, Ph.D. on self-disclosure of HIV serostatus to sexual partners and others, examining how individuals - both heterosexual and gay - make decisions about whether, what, when, and to whom to disclose.
