John Glendinning

Ann Whitney Olin Professor of Biology

Professor Glendinning joined the Barnard faculty in 1996. His research seeks to understand the physiological underpinnings one of life's great pleasures: eating. His current research is exploring how the sense of taste mediates behavioral and metabolic responses to sweeteners, complex carbohydrates and alcohol. He is also studying how pre- and post-natal experience with foods can make them taste better (or worse). He investigates these questions in rodents, using a combination of behavioral, electrophysiological, and molecular approaches.

In the News

In March, 2018, Barnard faculty members were awarded major research grants that support a range of research interests.

Barnard College was awarded a second Beckman Scholars Award to support student research in biology, chemistry, and neuroscience and behavior.

In the summer and fall of 2017, Barnard's exceptional faculty were awarded multiple prestigious research grants and fellowships.

Professor Alexandra Horowitz and Professor John Glendining dissect the differing ways in which humans and animals experience the world through smell and taste.

A new study authored by John Glendinning, the Ann Whitney Olin Professor of Biology, along with Ana Paula Morales Allende (’15) and Joyce Tang (’17) suggests that fetal alcohol exposure (FAE) reduces the taste system’s responsiveness to the bitter flavor and burning sensation of many varieties of alcoholic beverages.
