Our research is aimed at understanding the relationship between memory and energy intake in laboratory rats. Our findings show that excess intake of fat and/or sugar impairs hippocampal-dependent memory function. In another line of research we have shown that manipulations that disrupt hippocampal function increase energy intake. These clinically relevant findings suggest that obesity is characterized by a vicious cycle wherein impaired hippocampal functioning is both a cause and consequence of overeating. Our findings are also important for our basic understanding of how cognitive processes such as memory regulate eating.
Parent lab is composed of doctoral and undergraduate researchers conducting experiments examining the relationship between energy intake and memory in rodents. Our research typically involves obtaining behavioral measures of learning and memory, physiological measures of food intake, body weight, and body fat, as well as biochemical measures from brain, blood, and peripheral organs such as the liver.

Neurobiology of learning and memory in rats and human participants.
1) Effects of excess intake of fat and sugar and fatty liver on hippocampal-dependent function
2) Effects of memory on energy intake, particularly meal frequency
3) Effects of early life stress on memory and energy intake
