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.
