The focus of my laboratory has been the investigation of the autonomic control of cardiovascular function. We have in particular focused on baroreflex control, venous function and the cutaneous blood flow. We have used cutaneous blood flow as a model to examine autonomic control at the neurovascular junction and small fiber function.
