BioDr David M. Maahs is the Lucile Salter Packard Professor of Pediatrics, Division Chief of Pediatric Endocrinology, and Associate Chair for Academic Affairs in Pediatrics 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 Director of International Collaborations. This complements his role as President-elect for the International Society of Pediatric and Adolescent Diabetes (ISPAD, 2021-25) and Editor-in-Chief for the 2018 ISPAD Clinical Practice Consensus Guidelines. He served 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, prevent the complications of diabetes, and reduce disparities in diabetes care. He is author or co-author of over 350 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.' Dr Maahs is also the Associate Chair for Academic Affairs for the Department of Pediatrics.
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 adult children. -
Crystal Mackall
Ernest and Amelia Gallo Family Professor and Professor of Pediatrics and of Medicine
Current Research and Scholarly InterestsRecent 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.

Robbie Majzner
Assistant Professor of Pediatrics (Hematology/Oncology)
BioRobbie 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 InterestsMy 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.

Daphne O. Martschenko
Assistant Professor (Research) of Pediatrics (Stanford Center for Biomedical Ethics)
BioDaphne Martschenko, Ph.D., is an Assistant Professor at the Stanford University Center for Biomedical Ethics.
I hold an MPhil from the University of Cambridge in Politics, Development, and Democratic Education and in 2019 received a Ph.D. in Education, also from the University of Cambridge. My doctoral work investigated teacher perspectives on the role and relevance of genetic data for education, focusing on how behavioral genetics research on educational attainment and intelligence intersected with educators’ conceptualizations of racial and socioeconomic disparities in the American education system. I have appeared in numerous podcasts including Freakonomics Radio. I’ve had my work published in publicly accessible media outlets like Scientific American and The Conversation. My work advocates for and facilitates research efforts that promote socially responsible communication of and community engagement with social and behavioral genomics.
Currently I am writing a book with my friend and colleague Sam Trejo, a quantitative social scientist interested in how social and biological factors jointly shape human development across the life-course. In it, we unpack various social, ethical, and policy issues related to the DNA revolution. The floodgates of genetic data have opened, resurfacing age-old debates and raising new questions. We hope our book moves past the dichotomies—interpretivist vs. positivist, qualitative vs. quantitative, optimism vs. pessimism regarding biological explanations—that vex the biosocial sciences. -
