Unlocking the Potential of Digital Health

Our mission is to advance digital health research and applications by fostering an accessible health ecosystem at the Stanford Byers Center for Biodesign.

We develop, implement, and investigate digital health solutions that improve health journeys. 

Our flagship project, Stanford Spezi, is an open-source framework for building modular, interoperable, and scalable digital health applications.

News & Updates From Biodesign Digital Health


Students develop six Spezi-based real-world digital health applications

Students in our CS342 Building for Digital Health Course developed six real-world digital health projects using the Stanford Spezi framework in collaboration with faculty and clinicians at Stanford Health Care, Stanford Children's, and Charite Berlin.

Partner Project

Supporting Physical Activity Behavior Change with LLM-Based Conversational Agents

GPTCoach is a GPT4-based chatbot that implements an evidence-based health coaching program, uses counseling strategies from motivational interviewing, and can query and visualize a user’s health data from a wearable through tool use, built upon the Stanford Spezi framework.


CS342 Building for Digital Health Application

Are you excited about the intersection of healthcare and computer science?
Join CS342, Biodesign Building for Digital Health, this Winter Quarter! We are admitting students on a rolling basis, and there are only a few spots left:


CardinalKit published in JAMIA Open

In our newest publication in the Journal of the American Medical Informatics Association, we discuss the origins of the CardinalKit framework, the predecessor to Spezi, and how it facilitated the development of over a dozen applications for digital health research and clinical care across Stanford and beyond.

Partner Project

Increasing diversity in clinical trials

The OwnYourData team at Columbia University recently won a grant to increase diversity in clinical trials by enabling patients to aggregate and share their health information as well as access trials relevant to their condition, leveraging our Stanford Spezi framework and patient data access FHIR APIs.

Partner Project

Stanford students and faculty create a mobile app to help understand and treat pain

CHOIRMobile is a CardinalKit-based application that takes a novel approach to tracking chronic pain, by combining passively collected biometric data from wearable devices with validated pain assessments delivered periodically via a mobile app.

Partner Project

Digital solution for patients with cerebral palsy

Our BUDI team used CardinalKit to create an Apple Watch sensor-based interactive mobility program that helps patients with cerebral palsy perform therapy exercises anywhere while obtaining live biofeedback.

Partner Project

Making Digital Health Development More Accessible Through an Unlikely Collaboration

How a high school in New York uses our CardinalKit framework to teach digital health.
