I am the director of the Division of Cognitive and Behavioral Neurosciences in the Department of Neurology. I founded the Neurodiagnostic Laboratory at Buffalo General Hospital and I was the associate director of the Sleep Disorder Center of Western New York. I am a Diplomate in the American Board of Sleep Medicine and a Fellow in the American Psychological Association.
My research is in the area of cognitive and behavioral neuroscience with a particular interest in the neurophysiological basis of cognitive functioning, intellectual abilities, attention, and the role of sleep and sleep disorders, such as apnea, on neurocognitive functioning. The major methodological approach used in my laboratory is a combination of electrophysiological (mainly event-related brain potentials), neuropsychological, and other behavioral methods. Collaborative positron emission tomography (PET) and MRI studies have also been conducted and are being conducted in combination with electrophysiology. Both clinical and non-clinical populations are being studied. Populations studied have included infants, children, and adults, as well as animals. Recent work with clinical populations has focused on cognitive disturbances in autoimmune disorders such as Multiple Sclerosis and Systemic Lupus Erythematosus. In addition, recent research has been directed at brain mechanisms of cognitive control such as conflict resolution and response inhibition and how cognitive control is affected by PTSD symptomatology in working police officers. Other studies address the effectiveness of cognitive training in multiple sclerosis, and the efficacy of photobiomodulation therapy in treating TBI. The development of novel electrophysiological and behavioral markers of neural efficiency/neural noise and cognitive function via state-of-the-art dense electrophysiological techniques coupled with behavioral/cognitive paradigms is a significant focus of the research. In general, the research takes a systems approach to the understanding of cognitive functioning.
Research and clinical training/teaching are important functions of the Division. Over the years, our laboratory has mentored and trained undergraduate and graduate students, medical students, medical residents, and neuropsychology postdoctoral fellows/residents. We are closely affiliated with the Neuroscience Program and Psychology at UB and have students from both areas in our laboratory. Because of the scope of clinical and research areas of interest and the research tools available within the Division and via collaborations, unique multimethod opportunities are present for training and for examining research questions in unique and creative ways.
