New neurons (red) and microglia (green) in the hippocampus

My laboratory studies structural plasticity in the adult mammalian brain. We are interested in identifying the environmental, hormonal and neural stimuli that drive changes in the number, shape and size of neurons, astrocytes and microglia. The ultimate goals of our work are to determine the impact changes in brain structure have on cognition and anxiety regulation, as well as to identify factors that enhance plasticity and cell survival in the adult mammalian brain. We have been seeking to understand mechanisms of obesity-induced cognitive decline and have found that excessive weight gain decreases the number of synapses and changes microglial morphology. We have also been exploring mechanisms by which physical exercise enhances cognition and have found that running stimulates growth of neurons and astrocytes and this latter effect is linked causally with improved cognition.
