Jeffrey Armstrong

Jeffrey Armstrong, MD serves as an Associate Professor in the Department of Pediatrics at the University of California, Irvine School of Medicine. His academic appointment places him within the clinical faculty responsible for medical education, patient care, and research in pediatric medicine.

Dr. Armstrong's research focuses on the intersection of stress physiology and metabolic health in children and adolescents. His work investigates how cortisol regulation, stress responses, and early life exposures influence weight gain patterns and obesity development in youth. His research interests include pediatric endocrinology, developmental physiology, and the long-term health impacts of prenatal and early childhood exposures.

His notable publication examines cortisol reactivity patterns among adolescents with different prenatal drug exposure histories, revealing important connections between stress response systems and weight regulation. This research contributes to understanding the biological mechanisms underlying obesity development in vulnerable youth populations.

As a clinical faculty member in Pediatrics, Dr. Armstrong likely participates in medical student and resident education, clinical care of pediatric patients, and research mentorship, though specific teaching responsibilities are not detailed in the available materials.
