Lynnette Leidy Sievert is a biological anthropologist whose research has focused on age at menopause and symptom experience at menopause as two aspects of human variation. She is also interested in the evolution of menopause and post-reproductive aging as a human trait. As a Family Research Scholar, Leidy Sievert studied three interconnected aspects of everyday life: marriage and family, religion and spiritual practices, and economic security in relation to symptom experience among women at midlife.

She conducted this research in Mexico. She is currently working to understand variation in age and symptom experience at menopause in Puebla, Mexico; Asuncion, Paraguay; and Hilo, Hawaii. She has received funding in the past from the National Science Foundation, the Wenner-Gren Foundation for Anthropological Research, the AAAS, and UMass Amherst. She has also received the Young Investigator Award (twice) from the North American Menopause Society.
