Dr. Satchidananda (“Satchin”) Panda is a professor in the Regulatory Biology Laboratory at the Salk Institute for Biological Studies. His work focuses on chronobiology, the study of the day-night cycles that drive the multifaceted activities of the human body, using genetic, genomic, and biochemical approaches. He is an expert on circadian rhythms and a pioneer in the field of time-restricted eating. A priority for Dr. Panda when designing his studies is to identify strategies that positively impact public health.
Circadian rhythms, the body’s 24-hour cycles of biological, hormonal, and behavioral patterns, modulate a wide array of physiological processes, including the body’s production of hormones that regulate sleep, hunger, and metabolism, ultimately influencing body weight, performance, and susceptibility to disease. Circadian rhythmicity may have profound implications for human healthspan.
When and how much we sleep, eat, or exercise (and these activities’ effects on our health) are intrinsically linked to our circadian rhythms.
