Sleep, circadian rhythms and anxiety
Dr. Chellappa´s work has shown that sleep and circadian rhythms affect mood, cognition and brain activity in a variety of human populations, including healthy young and older adults, shift workers, patients with depression, patients with ocular diseases, and in individuals with neurodevelopmental conditions. Their work combines multimodal neuroimaging approaches to assess how sleep and circadian rhythms affect brain activity that modulate mood and cognition. Their work also includes sleep/circadian interventions to help improve mood, health and well-being using targeted light exposure and, more recently targeted nutritional interventions (meal timing) to improve cardiometabolic and mental health in humans.

Dr. Chellappa has authored more than 60 papers in prestigious journals including Science, Lancet, Science Advances, Nature Communications, Proceedings of the National Academy of Sciences of the United States, JAMA Ophthalmology, among others, and has consistently acquired funding to support their research. Dr. Chellappa is an active supporter of Diversity, Equity and Inclusivity, and is a neurodivergent self-advocate and a mental health lived expert.
