About
Our research focuses on the electrical excitability of the brain ranging from molecules to behavior. We are investigating the function of voltage-gated ion channels that confer excitability on neurons, the effect of channel properties on cell and circuit firing patterns, the neural control of behavior, and the relationship between spike activity and neuronal viability.
Our lab is trying to overcome these barriers and resolve the structures of several channels and transporters. This is an ideal format for students to interact with other groups and learn numerous techniques through interdepartmental collaborations.
