Ari Shechter, PhD

Profile Headshot

Overview

Ari Shechter is Assistant Professor of Medical Sciences at Columbia University Medical Center. Dr. Shechter received his PhD in neuroscience at McGill University, with a focus on human chronobiology. He then completed a postdoctoral research fellowship at the New York Obesity Nutrition Research Center at Columbia University. Dr. Shechter conducts laboratory-based experiments, observational studies, and clinical interventions to understand the biobehavioral pathways by which sleep and circadian rhythms influence health.

Research

Dr. Shechter's research examines how pathophysiologic states and behaviors associated with disrupted sleep and/or circadian rhythms, and their treatment, affect cardiometabolic and psychological outcomes. Areas of interest include obstructive sleep apnea, insomnia, shift work, and non-pharmacologic/behavioral approaches to improve sleep.

Research Interests

  • sleep and cardiometabolic health
  • insomnia
  • obstructive sleep apnea
  • circadian rhythms
  • food intake regulation
