Dan Iosifescu

Dr. Dan Iosifescu is the Director of Clinical Research at the Nathan Kline Institute and Associate Professor of Psychiatry at the New York University School of Medicine. His research is focused on novel pharmacological treatments (such as ketamine and other glutamatergic drugs) and devices (such as novel forms of magnetic stimulation) for patients with severe mood disorders (major depression and bipolar disorder). In his research, Dr. Iosifescu uses neuroimaging (MRI, MRS) and neurophysiology (quantitative EEG) techniques to evaluate structural, biochemical, and functional brain abnormalities in mood disorders and their impact on clinical treatment. In parallel, Dr. Iosifescu also focuses on the recognition and treatment of cognitive deficits associated with mood disorders.

After completing medical studies at the “Carol Davila” University in Bucharest, Romania, Dr. Iosifescu completed his internship and psychiatry residency at Massachusetts General Hospital (MGH) and McLean Hospital. His research training included a neuroimaging fellowship in the Neuroscience Laboratory at Harvard Medical School, a psychopharmacology fellowship in the MGH Mood and Anxiety Disorders Institute, and a fellowship in the Clinical Investigator Training Program at Harvard and MIT. In parallel, Dr. Iosifescu received a Master of Medical Science degree from Harvard University. Dr. Iosifescu was Associate Professor of Psychiatry at Harvard Medical School and a researcher at MGH until 2010; he then was the Director of the Mood and Anxiety Disorders Program and Associate Professor of Psychiatry and Neuroscience at the Icahn School of Medicine at Mount Sinai.

Dr. Iosifescu has authored more than 100 papers in peer-reviewed medical journals, 14 book chapters and more than 100 abstracts. He has received a series of prestigious prizes: the NARSAD Young Investigator Award (which he received twice), the Kaplen Award and the Livingston Award from Harvard Medical School, the American Psychiatric Association Young Investigator Award, the NCDEU New Investigator Award, and a National Institute for Mental Health K23 Career Development Award. Dr. Iosifescu has also been designated among the “Best Doctors in America” in all editions of “Best Doctors” since 2005, and among the Top Doctors in Castle Connolly’s psychiatry section.
