Nancy Long Sieber is an adjunct lecturer at the Harvard T. H. Chan School of Public Health. She received her BA with honors in biology from Oberlin College, and holds a PhD in physiology from the University of Michigan. Her PhD thesis was focused on studying the mechanisms of fever and stress hyperthermia. After spending a year as a postdoctoral fellow in Japan, she began her work at the Harvard T. H. Chan School of Public Health in 1991.

Sieber is broadly interested in environmental health, particularly its impact on vulnerable populations.

Her current work is focused on environmental health issues in India.

Sieber has been teaching at the Harvard Extension School since 1999. In addition, she currently teaches a course on human physiology in the Department of Environmental Health at the Harvard T.H. Chan School of Public Health, and a course entitled "Human Physiology: From Personal to Public Health" to Harvard College undergraduates.
