He also serves as service chief of the Gastroenterology, Nutrition, and Hepatology Clinic at Packard. From 2006 to 2008, he served as interim chair of the Department of Pediatrics.

Dr. Cox received his B.S. from Seattle University and his M.D. from the University of Washington. He completed his pediatrics internship and residency at the University of Oregon, followed by a fellowship in pediatric gastroenterology and nutrition at the University of California, Los Angeles. Dr. Cox went on to hold faculty positions at the University of California, Davis, University of Pittsburgh, and California Pacific Medical Center, before joining the Stanford faculty in 1995.

Dr. Cox is a fellow in the American Academy of Pediatrics, and a member of numerous professional societies including the Society for Pediatric Research, North American Society for Pediatric Gastroenterology and Nutrition, American Association for the Study of Liver Disease, and the Gastroenterology Association. He also serves as a reviewer for medical publications and Associated Editor for the Journal of Pediatric Gastroenterology and Nutrition. Dr. Cox has published 17 book chapters and more than 100 peer-reviewed articles in pediatric gastroenterology, hepatology and liver transplantation. One area of his recent research focuses has been gastrointestinal bacterial flora as a cause of autoimmune liver and intestinal disease.

 


 

Yinka Davies, M.D.

Yinka Davies, M.D. - Children's PSC FoundationYinka Davies, M.D., currently practices Pediatric Gastroenterology in the Sacramento Region.

Kari Nadeau, M.D., Ph.D.

Kari Nadeau, M.D., Ph.D. - Children's PSC FoundationKari Nadeau, M.D., Ph.D., Allergy, Immunology and Asthma. Our research interests in the laboratory focus on the role of human T cells, specifically natural regulatory T cells (Treg) and invariant natural killer T (iNKT) cells, in immunological diseases. We aim to differentiate the mechanisms of action of regulatory T cell suppressive function. We study how cells, such as iNKT cells, disrupt Treg suppressive function and how chemokines, like lymphotactin, enhance Treg suppressive function. As Principal Investigator, I have been working in the field of T cell tolerance for more than 15 years and I hypothesize that disruptions in the normal maintenace of tolerance by T cells lead to some human immune-mediated diseases. Our projects involve studying T cell functional mechanisms involved in the pathophysiology of human diseases such as allergic asthma, atopic dermatitis, systemic juvenile idiopathic arthritis, and primary immunodeficiencies. At Stanford, our laboratory is in a unique position, compared to other institutions, to effect translational scientific discoveries in these specific diseases since we have peripheral blood, tissue biopsies, and plasma from over 9 clinical studies occurring at Stanford. Our laboratory has many joint projects with other laboratories at Stanford such as the Mellins laboratory, the Lewis laboratory, and the Herzenberg laboratory.
