Albert M. Galaburda, MD, Director

Dr. Albert M. Galaburda has directed Cognitive Neurology since 1993. A native of Chile, he received his undergraduate and medical degrees from Boston University, and trained in Medicine under Norman Levinsky and in Neurology under Norman Geschwind, both at the Boston City Hospital (currently the Boston Medical Center). He received board certification in Internal Medicine in 1976 and in Neurology in 1977. Dr. Galaburda is the Emily Fisher-Landau Professor of Neurology (Neuroscience) at Harvard Medical School. His clinical and research expertise is in the field of cognitive neurology, with a special focus on learning and attention disorders, as they affect adults. He has had uninterrupted funding from the National Institutes of Health since 1981. He has published over 180 scientific articles and several books on these subjects, and has received many prizes and honors for his contributions to medical knowledge.

"One of the most enjoyable and rewarding aspects of being an academic neurologist is seeing, evaluating, and treating patients, where one can readily apply knowledge learned from work in the laboratory, and one can continue to get new ideas from listening to the patients. To cap it all, one can teach this new knowledge to the new generation of physicians and scientists, who will then push knowledge and quality of patient care to new levels through their own work."

"The great cardiac surgeon from my home state of Texas, Michael DeBakey, once was asked about the value of experience in a physician. He replied that when physicians say that they are 'experienced', too often they mean that they have been making the same mistakes for years. The greatest pleasure of working in an academic center like BIDMC is that I am surrounded by very insightful people to whom I can turn when I am in danger of 'making the same mistake'."

Daniel Z. Press, MD

Dr. Daniel Z. Press received his undergraduate degree from the University of Pennsylvania and his medical degree from the University of Connecticut School of Medicine.

Alvaro Pascual-Leone, MD, PhD

Dr. Alvaro Pascual-Leone trained in Neurology at the University of Minnesota after completing an M.D. and PhD in Neurophysiology at the University of Freiburg, Germany. He is board certified in Neurology and in Clinical Neurophysiology. After post-doctoral studies at the National Institutes of Health he joined the Spanish Research Council and the Cajal Institute, and in 1997 he returned to the US to join Beth Israel Deaconess Medical Center and Harvard Medical School.

He has authored over 300 scientific papers and is the recipient of several international honors and awards, including the Ramon y Cajal Award in Neuroscience (Spain), the Norman Geschwind Prize in Behavioral Neurology from the American Academy of Neurology, the Friedrich Wilhelm Bessel Research Award from The Alexander von Humboldt Foundation (Germany), and the Jean Signoret Prize from the Ipsen Foundation (Paris, France). His research aims at understanding the mechanisms that control brain plasticity across the lifespan to be able to modify them for the subject's optimal behavioral outcome. Pascual-Leone combines various brain imaging and brain stimulation methodologies to establish a causal relationship and a precise chronometry between regional brain activation and behavior, and uses noninvasive brain stimulation techniques to modulate brain plasticity, suppressing some changes and enhancing others, to gain a clinical benefit and behavioral advantage for a given individual. Such non-invasive approaches can lead to clinically relevant therapeutic effects in neuropsychiatry and neurorehabilitation, and serve as proof-of-principle prior to more invasive neuromodulatory interventions.

"It is a huge honor and a daunting responsibility when a patient trusts us to try to help him by translating cutting-edge results into clinical therapies and interventions. Frankly, I cannot imagine anything more rewarding than helping a patient and his family lead a healthier, happier life."
