In this webinar, Dr. George Roussos (Birkbeck College, University of London) gives an overview of PDkit, a Python-based open source data science toolkit to support data-driven systems using smartphones and wearables. Developed by Dr. Roussos’ team and supported by the Michael J. Fox Foundation, PDkit leverages wearables and mobile app data to support longitudinal investigations of disease mechanisms and progression. PDkit serves as an open source and scalable toolkit for high-frequency assessment of PD symptoms. To learn more about PDkit, you can also read Dr Roussos' post on our community platform. This webinar was organized by the the Michael J. Fox Foundation's Data Community of Practice (DCoP). Do you have ideas or suggestions for other webinar topics you would like to see?
