John Glendinning
Ann Whitney Olin Professor of Biology
Professor Glendinning joined the Barnard faculty in 1996. He studies the physiological mechanisms that control feeding in animals. Most of his projects focus on the contribution of taste to feeding, but he has recently begun to explore the effects of chemosensory feedback from the gut. Some of his current questions include:
- How does taste input interact with other feeding-related inputs (e.g., nutritive feedback from the gut) to stimulate or inhibit feeding?
- How does the peripheral taste system process the complex mixtures of chemicals that occur in food?
- How does experience (pre- or post-natal) with a food alter its orosensory properties?
- What is the relationship between sugar intake and weight gain?
- How does the taste system help animals feed in an adaptive manner—i.e., identify foods that are nutritious, toxic or medicinally beneficial?
He investigates these questions in mammals (mice and rats) and insects, using a combination of behavioral, electrophysiological, and molecular approaches.

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.
