Additional Information

Dr. Yang Roby, MD, PhD, is a Board-Certified Psychiatrist with over a decade of clinical experience in adult psychiatry and medico-legal psychiatric evaluation. She is the founder of Innerpeace Psychiatric Services, LLC, where she provides comprehensive psychiatric assessment and treatment for adults with complex psychiatric and neuropsychiatric conditions. Her clinical background includes extensive experience across inpatient, outpatient, emergency, consultation-liaison, geriatric, and dual-diagnosis settings. Dr. Roby’s expert witness and IME work focuses on psychiatric causation, threshold impairment, and differential diagnosis in civil and employment-related matters, with particular emphasis on work-related mental injury and disability determinations. She is frequently retained to evaluate whether reported psychiatric symptoms meet diagnostic and functional thresholds, the presence and role of pre-existing psychiatric vulnerability, and the extent to which workplace or situational factors are causally related versus contributory or incidental. A core area of Dr. Roby’s expertise is differential psychiatric assessment distinguishing trauma-related conditions from non-trauma neuropsychiatric syndromes, including mood disorders, neurocognitive disorders, sleep disorders, medical illness, and medication-induced psychiatric effects. Her clinical approach emphasizes careful review of records, symptom chronology, functional impact, and alternative explanations, allowing for structured and clinically grounded opinions in complex cases. Dr. Roby completed her residency training at the University of Iowa Hospitals & Clinics, with broad exposure to inpatient psychiatry, emergency psychiatry, addiction, geriatric psychiatry, and consultation-liaison psychiatry. She holds a PhD in Human Genetics & Neuroscience from the Johns Hopkins University School of Medicine, providing a strong foundation in neurobiology and medical-psychiatric integration that informs her evaluations without reliance on speculative or research-driven testimony. She is known for producing clear, well-organized reports that address specific legal questions regarding diagnosis, causation, functional impairment, capacity, and prognosis. Dr. Roby’s testimony style is neutral, methodical, and clinically focused. She accepts civil psychiatric matters, including IMEs and record reviews, and does not accept criminal cases, medical malpractice, custody, or divorce-related matters. Dr. Roby is licensed in Maryland and is fluent in English and Mandarin Chinese.
