My research is in the field of cellular neurobiology, focusing on a brain cell called the astrocyte. Astrocytes contribute to cognition through communication with neurons and other cells. We study factors involved in astrogenesis (growth of new astrocytes through proliferation) and causes of astrocyte dysfunction. Astrocyte dysfunction is an early predictor of neurological disease and the molecular mechanisms involved provide insight into disease etiology. On the cellular level, changes in the neuronal synapse have been associated with learning, and since astrocytes modulate synaptic communication and growth, this is disrupted if astrocytes are unhealthy. Similarly, local astrocyte proliferation is a normal process into adulthood, and determining what can stimulate or reduce this process could provide further understanding of cognitive processes or decline.
