Before becoming a pediatric surgeon, Dr. Claudia Mueller obtained her Ph.D. in Social/Personality Psychology at Columbia University under the supervision of Professor Carol Dweck. Dr. Mueller’s original graduate psychological research examined the effects of praise on children’s school outcomes and implicit theories or “mindsets” of intelligence. At Stanford, Dr. Mueller has expanded this research to focus on how children’s mindsets of health can influence their coping with illness and health outcomes. Working in collaboration with Professor Dweck, Dr. Mueller has developed and validated a novel measure of children’s health mindsets (Health Belief Scale). She has used this scale to demonstrate differences in health behaviors in both healthy and chronically-ill children, particularly in the area of Type 1 diabetes. Dr. Mueller is currently working to develop an intervention which can change children’s health beliefs and improve their health outcomes.

Dr. Mueller is also interested in physician wellness and is the Co-Director of the Stanford Department of Surgery's Balance in Life Committee, which focuses on resident well-being.  

Her clinical interests include general pediatric and neonatal surgery.  She is the Medical Director of Stanford Children's Health at CPMC and spends most of her clinical time at California Pacific Medical Center in San Francisco.

Dr. Powell grew up the Midwest fully expecting to become a shortstop for the Chicago Cubs. His career plans turned to medicine while an undergraduate at Johns Hopkins when it became clear he could not hit a big league curve ball. During medical school, Dr. Powell was exposed to many great surgeons who taught him the benefit of accumulating first-hand experience, problem solving, and the fulfillment of saving lives. After establishing a thriving pediatric surgical practice, Dr. Powell was fortunate enough to be accepted into the transformative inaugural Master Teacher in Medical Education Program. Dr. Powell's teaching philosophy centers on the belief that every surgeon wants to take better care of their patients. After twenty-five years of trainees, colleagues, collaborators and programs, that philosophy has yet to be proven wrong.

Dr. Powell also enjoys golf, sailing, fly fishing, and having the experience of age that allows him to hit the occasional curve ball when it is metaphorically thrown at him.

Dr. Sylvester concurrently pursues three areas of related investigation. The general approach of his efforts are to combine the study of human disease samples and mouse models of human disease to pose new hypotheses and to test these hypotheses experimentally. The objective of Dr. Sylvester's studies is to derive a deeper understanding of human disease and to develop applications for possible new diagnostics and therapeutics. 

In the laboratory the group studies the role of Wnt signaling in liver regeneration and response to injury. The Sylvester laboratory has demonstrated that Wnt and its signaling molecule beta-catenin have a strong influence over hepatocellular metabolism and resistance to oxidative stress. Ongoing studies to gain a deeper understanding of the mechanism by which Wnt and related pathways exert control over cellular metabolism, energy balance and redox balance are ongoing. Cellular energy and redox balance are central to the related processes of liver development, regeneration and tumorignesis. 

Dr. Sylvester has established a network of academic children's hospitals and investigators to study the human newborn diseases Necrotizing Enterocolitis and sepsis. The group has published several papers describing their novel findings of molecular indicators or biomarkers of disease. The group is seeking to establish both molecular indicators of disease as well as biochemical indicators that accurately identify infants most at risk for disease in order to provide clinical strategies to prevent disease onset. Molecules and pathways of interest that have been identified in human specimens are studied further in experimental models of disease to gain a deeper insight to the specific mechanisms of disease.
