Robert Phillips

Degree: Ph.D. Purdue University, 2000

Research Interests:

Dr. Phillips’ research focuses on the autonomic nerve circuits with which the brain coordinates gastrointestinal tract functions and regulates food intake.

Recently, he has concentrated on how these nerve circuits change and become impaired with age. Phillips’ focus on the aging of the circuitry controlling digestion and ingestion addresses important health problems of the elderly and simultaneously provides a unique perspective to better understand the neural pathways that control food intake.
