Carole Scherling, PhD

Postdoctoral Scholar

Carole Scherling, PhD, is a postdoctoral student at the UCSF Memory and Aging Center. After undergraduate work at the University of Ottawa, she completed a masters degree in neurological sciences at McGill University and a doctorate in behavioral neurosciences at the University of Ottawa. Her past research focused on mild clinical impairments in both healthy and clinical populations using MRI and fMRI techniques, neuropsychological assessments and biological markers. Her current research centers on behavioral and neurophysiological measurements of insight and cognitive abilities in patients with neurodegenerative disease.

Dena Dubal, MD, PhD

Assistant Professor of Neurology

Dr. Dubal received her MD and PhD degrees from the University of Kentucky College of Medicine. Her graduate research with Dr. Phyllis Wise focused on effects of hormones on stroke injury. Dr. Dubal completed a medical internship and neurology residency at UCSF, where she also served as chief resident. She then trained with Drs. Lennart Mucke and Bruce Miller, who shared the 2011 Potamkin Prize in Neurodegeneration. Dr. Dubal is an Assistant Professor of Neurology at UCSF and directs the Laboratory of Neuroscience and Aging research. Her laboratory's research focus is on how to slow or block aging to prevent diseases of the aging brain, such as Alzheimer's. She is a recipient of the Paul Beeson Career Development Award through the NIA and American Federation for Aging Research.

Georges Naasan, MD

Neurologist, Clinical Instructor

Dr. Georges Naasan received his medical degree from the American University of Beirut in Lebanon. He completed an internship in medicine and a residency in neurology at Case Western Reserve University, University Hospitals of Cleveland. He joined the UCSF Memory and Aging Center in 2011 where he is a Clinical Instructor and a Behavioral Neurology Fellow.

As a neurologist, Dr. Naasan evaluates patients and research participants with various neurodegenerative disorders through a multidisciplinary approach and provides follow-up care. He is particularly interested in the psychotic manifestations of neurodegenerative diseases such as hallucinations and delusions. During his residency, he used functional MRI imaging techniques to study the anatomy of misidentification delusions such as the Capgras syndrome.
