His current research interests include the neural basis of respiration, dynamics of bursting neurons, intrinsic and synaptic mechanisms for synchronization, and conduction properties of peripheral nerve and their block by high frequency stimulation. His approaches include single neuron models, complex neuron models, electrophysiology experiments, and the use of the dynamic clamp. Robert believes strongly in the value of complementary skills and perspectives, and as a result has multiple collaborative funded projects with both modelers and experimentalists.
