Iris Titos Vivancos is an Assistant Professor in the Department of Biochemistry and Molecular Genetics at Northwestern University's Feinberg School of Medicine. Her academic focus lies in understanding how behaviors are elicited by external stimuli and internal states. This research aims to synchronize actions with needs, enhancing responses to food stimuli, particularly when hunger is present. The significance of these internal states and their origins through signaling pathways is a central theme of her work. Historically, the study of internal states has been concentrated on the brain, yet Vivancos emphasizes the role of peripheral organs in influencing behavior through a repertoire of signals. Her laboratory investigates gut signaling pathways that communicate nutritional status to the brain, illustrating how internal states can affect behaviors such as sleep and preference for substances like amphetamines. Vivancos’ work thus contributes to a broader understanding of the mechanisms that regulate internal states and their behavioral implications.
