The Stanford Team

Abby King

Faculty Director

Dr. King, PhD, is a professor of Health Research and Policy and of medicine at the Stanford Prevention Research Center. She leads an interdiscplinary research team aimed at creating cutting-edge behavioral and technological programs promoting the healthy lifestyles necessary for living long and productive lives. Her teams' borderless health promotion solutions seek to create health programs that break down barriers related to education, literacy, language, and computer knowledge and access.

Sandra Winter


Sandra, PhD, MHA, is the Director of the Our Voice Initiative and the Wellness Living Laboratory (WELL). Her research areas of interest include community-based interventions among under resourced populations, particularly in a global context. She is also interested in using technology to promote physical activity in tech-naiive older adults and using a citizen science engagement model to empower community residents to advocate for changes in their neighborhood to better support healthy, active living. 


Ann Banchoff

Director of Community Engagement

Ann Banchoff, MSW, MPH, has a background in public health, social work, and international human rights, as well as broad experience in developing and sustaining community-academic partnerships.  She has worked extensively with migrants and other underserved populations in the California Bay Area and in Oaxaca, Mexico, and has also lived and worked in Russia, France, Ethiopia, and Peru.  Ann co-founded the Office of Community Health at the Stanford University School of Medicine in 2005, and served as its Director of Educational Programs until late 2014.  

Jylanna Sheats

Dr. Jylana L. Sheats is an Assistant Professor of Nutrition at the Tulane University School of Public Health and Tropical Medicine (TUSPHTM) in the Department of Global Community Health and Behavioral Sciences. Her research focuses on the design and implementation of community and/or technology-based interventions that aim to reduce obesogenic behaviors among racial/ethnic minority and underserved populations; and the assessment of environmental factors that contribute to these negative health behaviors and poor health outcomes. Dr. Sheats was previously a researcher at the Stanford Healthy Aging Research and Technology Solutions (HARTS) Lab, where she directed and co-directed the design and/or testing of a series of NIH-funded RCTs that utilized technology to increase physical activity or healthy eating among aging racial/ethnic minority populations.

Lisa Goldman Rosas

Dr. Goldman Rosas is an epidemiologist whose research features engagement of patients, communities, and other key stakeholders to promote health equity in the US and globally. With funding from NIH, AHRQ, and PCORI, her research methods include randomized controlled trials as well as mixed methods to produce robust evidence that can be translated into effective, practical, and scalable strategies to reduce the prevalence of chronic disease in populations that bear the greatest burden. In addition to research, she teaches at the undergraduate and graduate levels and has a special focus on increasing diversity in biomedical research.

Naina Ahuja

Research Assistant

Naina earned her Bachelor in Science in Public Health Science and Psychology with a minor in Biology at Santa Clara University. Her previous research concentrated on increasing physical activity amongst low socioeconomic mothers. Naina exhibits a passion for creating effective and targeted physical activity interventions and helping improve the lives of others. She also has experience working with children in different realms and applying Cognitive Behavioral Therapy. Currently, Naina is assisting with the citizen science work in Santa Clara County within the Wellness Living Laboratory.

Ben Chrisinger

Postdoctoral Fellow

With a background in urban planning and environmental sciences, Dr. Chrisinger is committed to research that helps us understand relationships between the built environment and health, especially health disparities. Dr. Chrisinger is the co-Principal Investigator (Dr. Abby King, co-PI) for a pilot study, Stress Experiences in Neighborhood and Social Environments (SENSE), that initiates a new line of inquiry using physiological data to better understand individuals' neighborhood perceptions within the Our Voice model. His previous research has examined efforts to open new supermarkets in underserved areas ("food deserts") by considering development processes, store-level outcomes, and community and customer experiences. With the Citizen Science Initiative, he also has coordinated an Our Voice research partnership between with stakeholders in Camden, New Jersey to assess the city's healthy corner store initiatives.

Jenna Hua

Postdoctoral Fellow

Jenna's, RD, MPH, PhD, registered dietitian and environmental health scientist by training, research interests include mHealth, N-of-1 studies, health impacts of the built environment, obesity and chronic disease intervention and prevention, global health, as well as “omics” technologies in personalized medicine. Jenna’s doctoral research at UC Berkeley investigated built environment exposures and social risk factors, and their associations with the nutrition transitions in China using health technologies such as ecological momentary assessment (EMA), personal mobility tracking and ambulatory monitoring. Jenna is committed to use multi-disciplinary approaches and new technologies to develop and implement cost-effective, sustainable and scalable tools and solutions for researchers, educators, public health practitioners and policy makers to use in order to promote healthier lifestyles and create better built environment.

Sparkle Springfield

Postdoctoral Fellow

Dr. Springfield completed her doctoral training in Kinesiology, Nutrition, and Rehabilitation at the University of Illinois at Chicago. Her research is focused on gaining a more in-depth understanding of the factors that contribute to poor dietary and physical activity outcomes in African American women. She is particularly interested in exploring how technology-based platforms such as Our Voice can be used as a tool to increase community engagement and support positive behavior change in this population.
