Leading new feature development and special projects for Fitabase, a data management and analytical tool wearble devices deployed in research studies and healthcare innovation projects.
2014-2106 Program Director, Quantified Self Labs
Co-led the direction of Quantified Self Public Health program (funded by the Robert Wood Johnson Foundation). Managed the Quantified Self Public Health Symposium, bringing together multiple stakeholders in government, academia, and industry. Led program development for the Quantified Self Global and European Conferences. Conducted research on self-tracking and communicated about Quantified Self at conferences and events.
Community Organizer, Quantified Self Labs
Coordinated the communication strategy for a worldwide network of meetup leaders. Managed speakers for multiple conferences. Edited and managed the QuantifiedSelf.com website.
Graduate Research Assistant, Center for Wireless and Population Health Systems (UCSD)
Designed and coordinated field studies of wearable activity devices. Developed deployment and data analysis protocols for accelerometer, GPS, and other wearable bio-sensors for research studies. Conducted secondary data analysis, and coordinated peer-reviewed research articles. Co-taught undergraduate public health courses.
Ph.D. Public Health (Health Behavior). San Diego State University/University of California, San Diego
Dissertation: Discretionary self-monitoring of physical activity: A mixed-methods study of behavior change technique use and historical physical activity. Designed and conducted a study of long-term users of physical activity trackers (Fitbit) using qualitative and quantitative data. Explored real-world behavior change techniques and their potential impact on activity behavior in 30 individuals.
