Professor of Pediatrics (Endocrinology) and, by courtesy, of Epidemiology and Population Health at the Lucile Salter Packard Children's Hospital and at the Stanford University Medical Center
Bio Dr David M. Maahs is Professor of Pediatrics and Division Chief of Pediatric Endocrinology at Stanford University and the Lucile Packard Children?s Hospital. He earned his MD followed by Pediatric Residency at the University of New Mexico. After 3 years on New Mexico?s faculty, Dr. Maahs completed a Pediatric Endocrinology fellowship and a concurrent PhD in Epidemiology at the University of Colorado. He remained on Colorado?s faculty for 10 years, advancing to Professor of Pediatrics before moving to Stanford. Prior to his medical career, Dr. Maahs received a BA and MA in English from the University of Kansas and was inspired to pursue a medical career after serving in the Peace Corps with assignments in Tunisia and the Central African Republic.
Dr. Maahs? leadership experiences include being a past co-Chair (2013-16) for Protocols and Publications with the Type 1 Diabetes Exchange for which he continues as a Steering Committee member and Director of International Collaborations. This complements his role as Secretary-General for the International Society of Pediatric and Adolescent Diabetes (ISPAD, 2016-20) and Editor-in-Chief for the 2018 ISPAD Clinical Practice Consensus Guidelines. He currently serves on the Professional Practice Committee for the American Diabetes Association (ADA, 2016-18), which writes the annual ADA Standards of Care. Previously, he served on the ADA Scientific Sessions committee representing the Council on Youth. He has also served on national committees for the American Heart Association, the Pediatric Endocrine Society, and multiple journal editorial boards and review committees.
His scholarly interest is improving care and preventing complications in people with type 1 diabetes (T1D). Along with Dr Peter Chase, he is author of the 12th and 13th editions of Understanding Diabetes, or ?Pink Panther,? which are the most widely used educational books for children newly diagnosed with T1D, distributed internationally by the Juvenile Diabetes Research Fund (JDRF). More specifically, he has conducted epidemiologic studies that help generate hypotheses for clinical studies, including trials to develop artificial pancreas systems to improve glucose control, lower disease burden, and prevent diabetic complications. He is author or co-author of over 300 research publications. His multi-disciplinary research has been funded by the JDRF, the National Institutes of Diabetes and Digestive and Kidney Diseases (NIDDK), the Helmsley Charitable Trust, and the National Science Foundation (NSF).
Dr Maahs is Associate Director for the recently formed and NIDDK P30 funded Stanford University Diabetes Research Center (https://sdrc.stanford.edu). His collaborations extend to his role as Principal Investigator (PI) or steering committee member for NIH funded multi-center clinical trials including the FLEX, PERL, and ACTION studies as well as multiple Artificial Pancreas clinical trials. Education, mentorship, and training leadership includes being Program Director with Dr. Georgeanna Klingensmith on the Barbara Davis Center T32 and K12 training grants in Pediatric Endocrinology while at the University of Colorado. He is the PI on the Stanford NIH funded K12 "Training Research Leaders in Type 1 Diabetes.'
While in the Peace Corps, David met his wife, Christine Walravens, who is also a Pediatrician at Stanford. They enjoy outdoor activities and traveling with their children, Nicholas (22) and Natalia (16).
Ernest and Amelia Gallo Family Professor and Professor of Pediatrics and of Medicine
Current Research and Scholarly Interests Recent clinical studies, by us and others, have demonstrated that genetically engineered T cells can eradicate cancers resistant to all other therapies. We are identifying new targets for these therapeutics, exploring pathways of resistance to current cell therapies and creating next generation platforms to overcome therapeutic resistance. We have discovered novel insights into the biology of human T cell exhaustion and developed approaches to prevent and reverse this phenomenon.
David Magnus, Ph.D.
Thomas A. Raffin Professor in Medicine and Biomedical Ethics and Professor (Teaching) of Medicine (Primary Care and Population Health)
Current Research and Scholarly Interests Genetic testing, gene therapy, genetically engineered organisms, and the history of eugenics. Stem cell research and cloning, and egg procurement. Examining ethical issues in reproductive technologies. Organ transplantation – including donation after cardiac death, ethics of listing decisions. End of life issues in both adults and children.
Assistant Professor of Pediatrics (Hematology/Oncology) at the Stanford University Medical Center
Bio Robbie Majzner is an Assistant Professor of Pediatrics in the Division of Hematology and Oncology. After graduating with a BA from Columbia University, Dr. Majzner attended Harvard Medical School, where he developed an interest in pediatric oncology. He completed his residency training in pediatrics at New York Presbyterian-Columbia and fellowship training in pediatric hematology-oncology at Johns Hopkins and the National Cancer Institute. During his fellowship, he cared for some of the first pediatric patients to receive CD19 chimeric antigen receptor (CAR) T cells, children with B cell acute lymphoblastic leukemia (B-ALL) who often had no other therapeutic option. Witnessing the success of CAR T cells in these patients drove Dr. Majzner to the laboratory, where he focuses on extending the use of CAR T cells to solid tumors. He has generated and optimized novel receptors to recognize antigens over-expressed on pediatric solid tumors such as GD2 (Mount/Majzner et al., Nature Medicine, 2018) B7-H3 (Majzner et al., Clinical Cancer Research, 2019), and ALK (Walker/Majzner et al., Molecular Therapy, 2017). Current work focuses on imparting multi-specificity to CAR T cells and optimizing these receptors to enhance their efficacy when the amount of target (antigen density) is limiting (Majzner et al., Cancer Discovery, 2020). By drawing on state of the art bioengineering techniques, the Majzner Laboratory focuses on enhancing the potency and specificity of CAR T cells for children with cancer.
Clinically, Dr. Majzner cares for all patients with neuroblastoma at the Lucile Packard Children's Hospital and has a specific interest in bringing novel immunotherapies to clinical trials for these patients and those with other solid tumors. He is board certified in pediatrics and pediatric hematology-oncology.
Senior Associate Dean, Faculty Development and Diversity, Taube Professor of Global Health and Infectious Diseases, Professor of Pediatrics (Infectious Diseases) and of Epidemiology and Population Health
Current Research and Scholarly Interests My research focuses on epidemiologic aspects of viral vaccines and perinatal HIV infection. This includes the molecular epidemiology of factors affecting the immunogenicity of oral polio vaccine (OPV) in developing areas of the world, and now the epidemiology of transmission and circulation of vaccine derived polioviruses in order to assist in global eradication of polio. I also work in development of methods to prevent breastfeeding transmission of HIV in Africa.
