Research Focus

The Grill lab studies candidate intracellular coordinators of neuronal development. By unraveling the mechanisms by which these molecules function, we will gain insight into how neurons integrate and manage numerous signals from their environment to form a neural network. We also hope to identify key molecular functions that can be stimulated to trigger new synapse and axonal growth. Such knowledge has tremendous potential to aid in generating new therapies to treat neurodegenerative diseases, and injury to the central nervous system from stroke.
