    Dr. New is Professor, Residency Training Director  and Vice Chair for Education in the Department of Psychiatry at Mount Sinai. Dr. New has a longstanding career as a funded principal investigator studying the neurobiology of borderline personality disorder. Her research focus is on emotion dysregulation and emotional interoception abnormalities in borderline personality disorder, symptom domains which underlie some of the interpersonal difficulties encountered in this disorder. In addition, Dr. New explores individual differences in response to stress and trauma, focusing on how this relates to emotion regulation. She uses brain imaging techniques, genetic studies, and laboratory assessment of behavior to explore neural circuitry and mechanisms of treatment response in BPD.  In addition, Dr. New has been a teacher and mentor to medical students, residents and post-doctoral fellows throughout her career. She was Director of Medical Student Education in the Department of Psychiatry at The Icahn School of Medicine at Mount Sinai prior to rising to the position of Residency Training Director and Vice Chair for Education. Dr. New has won several awards for teaching and scholarship. She completed her residency in psychiatry at New York Hospital/ Payne Whitney Clinic and a postdoctoral research fellowship at Mount Sinai.

Dr. New's research focuses on the neurobiology of borderline personality disorder.  Her work explores the regulation of emotion in this disorder using techniques such as functional and structural brain imaging, psychophysiology, neurocognitive tasks and techniques in social neuroscience.  Her work has examine the neural circuitry underlying the control of aggression, but more recently has employed a theoretical framework from the philosophy of mind to understand the experience of emotion in this complex disorder.

In addition to borderline personality disorder, Dr. New explores the effect of trauma in women with particular focus on factors that create vulnerability and resilience to adverse consequences of traumatic experiences, also employing functional brain imaging and neurocognitive tasks.
