Michael Ma
Assistant Professor of Cardiothoracic Surgery (Pediatric Cardiac Surgery)
Current Research and Scholarly InterestsOur lab aims to understand the biomechanics that govern a wide spectrum of congenital heart defects, and how those biomechanics change with contemporary operative repair strategies. We simulate operations virtually via CFD, and in ex vivo and in vivo animal models, and analyze how the changes we make alter fluid flow, pressure, and stresses throughout the system. We hope that these experiments can impact and optimize existing techniques that translate quickly to the operating room.

Xinru Ma
Research Scholar
BioXinru Ma’s research focuses on nationalism, great power politics, and East Asian security with a methodological focus on formal and computational methods. More broadly, Xinru’s research encompasses three main objectives: Substantively, she aims to better theorize and enhance cross-country perspectives on critical phenomena such as nationalism and its impact on international security; Methodologically, she strives to improve measurement and causal inference based on careful methodologies, including formal modeling and computational methods like natural language processing; Empirically, she challenges prevailing assumptions that inflate the perceived risk of militarized conflicts in East Asia, by providing original data and analysis rooted in local knowledge and regional perceptions. Her work has been published in the Journal of East Asian Studies, The Washington Quarterly, the Journal of Global Security Studies, and the Journal of European Public Policy, and in edited volumes through Palgrave. Her co-authored book - Asian Power Transitions: Internal Challenges, Common Conjecture, and the Future of U.S.-China Relations - is forthcoming with the Columbia University Press.
At SNAPL, Xinru will lead the research group in collaborative projects that focus on U.S.-Asia relations. One of the projects will contrast the rhetoric and debates in US politics surrounding the historical phenomenon of "Japan bashing" and the current perception of a "China threat.” By applying automated text analysis and qualitative analysis to textual data from various sources such as congressional hearings and presidential speeches, this project uncovers the similarities, differences, and underlying factors driving the narratives surrounding US-Asia relations. She will also provide mentorship to student research assistants and research associates.
Before joining SNAPL, Xinru was an assistant professor at the School of International Relations and Diplomacy at Beijing Foreign Studies University, where she led the Political Science Research Lab, a lab committed to closing the gender gap in computational methods and political science research by offering big data methods training and professionalization workshops to students. Prior to that, Xinru was a post-doctoral fellow at the Center for International Security and Cooperation at Stanford University (2019-2020), and a pre-doctoral fellow at the Department of Political Science at Vanderbilt University (2018-2019). In 2023, Xinru was selected as an International Strategy Forum fellow by Schmidt Futures, an initiative that recognizes the next generation of problem solvers with extraordinary potential in geopolitics, innovation, and public leadership. -
David Maahs
Lucile Salter Packard Professor of Pediatrics and Professor, by courtesy, of Epidemiology and Population Health
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.
