Sayantani Sindher (Tina), MD

Director of the Clinical Translational Research Unit

 Read bio 

Dr. Sindher completed her Pediatric residency at Albert Einstein College of Medicine, Children’s Hospital at Montefiore in Bronx, NY and her fellowship in Allergy and Immunology at Children’s Hospital of Philadelphia (CHOP), Philadelphia, PA. She joined the Sean N. Parker Center for Allergy & Asthma Research (SNP center) at Stanford University in January 2017 and is now the Director of the Clinical Translational Research Unit. Dr. Sindher divides her time between clinical research trials at the Sean N. Parker Center for Allergy and Asthma Research (SNP) center and the Oral Immunotherapy Clinic at Lucille Packard Children’s Hospital (LPCH), which is focused on the care of pediatric allergy and immunology patients. Dr. Sindher is the principal investigator of several clinical trials addressing atopic conditions including food allergy, atopic dermatitis, and asthma. Her present interests lie primarily in food allergy and eosinophilic esophagitis research involving strategies for prevention, diagnostics, and novel therapeutics.

Scott Boyd, MD, PhD

Director of the Parker Lab

 Read bio 

Dr. Boyd is a physician scientist who is the director of the Parker Lab and a Stanford Professor in Food Allergy and Immunology and Professor of Pathology. He received bachelor's degrees in Biochemistry at the University of Manitoba, and English Literature at Oxford University, where he was a Rhodes Scholar. He obtained his M.D. from Harvard Medical School and Ph.D. from MIT, followed by pathology residency, hematopathology fellowship, and postdoctoral research work at Stanford University. He is a recipient of the Presidential Early Career Award for Scientists and Engineers, among other honors. The Boyd laboratory uses high-throughput DNA sequencing and single-cell experiments to analyze human immune responses to infection and vaccination, as well as immunological disorders such as food allergy and immunodeficiency. Many of the laboratory’s projects analyze the responses of B cells and the genetics and functional roles of antibodies in health and disease.
