Santange, who is an associate professor of nutritional medicine at Columbia University,

where she also serves as the director for the Center of Excellence for Sleep and Circadian Research.

Her research primarily focuses on the interplay of various lifestyle factors,

0:33.8

but most notably on this interplay between diet and sleep and how they impact a range of

0:41.9

outcomes, but particularly looking at things like cardiovascular risk factors, energy balance,

0:47.6

and so on. So she's been conducting clinical studies that explore how things like sleep duration,

0:53.4

sleep timing, meal timing,

0:55.8

and then eating patterns all can influence our energy intake, how these might have a role
