Dr. Earth Hasassri is a Clinical Fellow of Child & Adolescent Psychiatry within the Department of Psychiatry and Behavioral Sciences at Stanford University School of Medicine and Lucile Packard Children's Hospital at Stanford. He specializes in seeing patients for complex psychiatric conditions such as psychotic experiences and autism spectrum disorders. His interests are caring for individuals who suffer from medical conditions at the interface of medicine and psychiatry. In addition, he treats children with a broad range of psychiatric disorders including neurodevelopmental disorders, ADHD and mood and anxiety disorders in adolescents.

Prior to medical school, Dr. Hasassri graduated with dual bachelor's degrees in neurophysiology and psychology at the University of California San Diego, where he performed research on sleep medicine. He earned his medical degree from the Mayo Clinic Alix School of Medicine where he did research in clinical epidemiology. Dr. Hasassri completed his residency in general psychiatry at the University of California San Francisco Langley Porter Psychiatric Hospitals & Clinics, during which he was awarded an Area of Distinction in Clinical Neuroscience for his work in applying neuroscientific principles in his clinical work in those with brain cancer, dementia, neurodevelopmental disorders, and other neuropsychiatric conditions. Dr. Hasassri is a board certified general psychiatrist and is currently pursuing further training through a fellowship here at Stanford to obtain subspecialty board certification in child and adolescent psychiatry.

Dr. Hasassri's scientific interest focus on bringing novel interventional treatments to children and adolescents, such as transcranial magnetic stimulation. He is currently working with Dr. Nolan Williams and Dr. Antonio Hardan in their laboratories studying whether transcranial magnetic stimulation is safe and effective for children and adolescents, particularly in those with autism spectrum disorders.
