Research and Academic Interests: 

Dr. Barton's current research interest is Physiologic Informatics, which is the application of signal processing algorithms and methods to clinical data and using these methods to describe associations to clinical outcomes. Currently, he is focusing on acute neurologic emergencies, e.g., stroke, traumatic brain injury, and computing the "dose" of hypertension or hypotension and showing its relationship to neurologic outcome.

In collaboration with Dr. Claude Hemphill, Director of Neuro-Critical Care, he has developed a novel method to evaluate the impact of abnormal vital signs in the prehospital setting and in the ED on secondary brain injury. They have shown that the new method - using the area under the curve - is a more accurate method of assessing secondary brain insults in acute neurologic emergencies. In addition to this work, Dr. Barton joined the UCSF-SFGH Brain and Spinal Cord Injury (BASIC) group, a consortium of Neurosurgery, Neurology and Emergency Medicine Clinical Investigators.
