Vishnu Ravi is a technology architect with a background as a physician and software engineer, focusing on creating innovative digital health solutions that support research and improve clinical care at Stanford Medicine. During his medical training, he did early work on clinical applications for conversational agents and extracting insights from unstructured health data. He has also co-founded a digital health startup, developed solutions for COVID-19 that were deployed internationally, and contributed to the first family of international mobile health data standards via the IEEE.

As the Lead Architect of the Building for Digital Health program at the Stanford Byers Center for Biodesign, Vishnu has led the development of the Stanford CardinalKit digital health framework and co-created its successor, Stanford Spezi. CardinalKit and Spezi have been used to create over 20 digital health clinical and research applications at Stanford and other leading healthcare and research institutions. Vishnu has also been an instructor for CS342/MED253, a real-world digital health app development course for Stanford computer science undergraduates and graduate students, since 2021.

Vishnu is currently the Technology Architect for Catalyst, Stanford Medicine’s flagship innovation program to support inventors across the Stanford community in developing and accelerating their most promising innovations for transformative health, which spans digital health, diagnostics, and therapeutics.

    Smartphone devices capable of monitoring users' health, physiology, activity, and environment revolutionize care delivery, medical research, and remote patient monitoring. Such devices, laden with clinical-grade sensors and cloud connectivity, allow clinicians, researchers, and patients to monitor health longitudinally, passively, and persistently, shifting the paradigm of care and research from low-resolution, intermittent, and discrete to one of persistent, continuous, and high resolution. The collection, transmission, and storage of sensitive health data using mobile devices presents unique challenges that serve as significant barriers to entry for care providers and researchers alike. Compliance with standards like HIPAA and GDPR requires unique skills and practices. These requirements make off-the-shelf technologies insufficient for use in the digital health space. As a result, budget, timeline, talent, and resource constraints are the largest barriers to new digital technologies. The CardinalKit platform is an open-source project addressing these challenges by focusing on reducing these barriers and accelerating the innovation, adoption, and use of digital health technologies. CardinalKit provides a mobile template application and web dashboard to enable an interoperable foundation for developing digital health applications. We demonstrate the applicability of CardinalKit to a wide variety of digital health applications across 18 innovative digital health prototypes.
