• Professor, Dept Of Internal Medicine

Research Statement

His research has three areas of focus: adverse drug events, human interface design, and scientific computing. His work concerning the characterization, epidemiology, and prevention of adverse drug events is widely cited. Much of this work concerns how EHRs help or don’t help prevent these events. More recently, he has focused on translating basic science of cognitive and social psychology to medical informatics and EHR design. Randomized controlled trials of his novel user-interface designs have demonstrated increased accuracy of and decreased time to diagnosis of medical conditions. He is helping incorporate these lessons into the design of VA’s EHR systems. Previously, he led the establishment of VA’s scientific computing center and led architectural work for technologies to support epidemiology and natural language processing.
