Moody PhysioNet Challenges

In cooperation with the annual Computing in Cardiology (CinC) conferences, PhysioNet also hosts an annual series of biomedical ‘Challenges’ that focus on unsolved problems in clinical and basic science. These Challenges have been supported by the NIH, Google, MathWorks and the Gordon and Betty Moore Foundation. For the first 15 years (from 2000 to 2014), these Challenges were led by George Moody, at the Laboratory for Computational Physiology (LCP), who subsequently retired due to poor health. Since 2015, the Challenges have been led by Gari Clifford at Emory University and the Georgia Institute of Technology. In honor of George’s lifelong contributions to the field, and particularly his seminal work on the Challenges, the Challenges were renamed from the ‘PhysioNet/Computing in Cardiology Challenges’, to the ‘George B. Moody PhysioNet Challenges’ in 2021.

If you are interested in contributing to, or posing a Challenge, please see Organizing a Moody PhysioNet Challenge here.

Past Moody PhysioNet Challenges

A list of past Challenges, with links to the descriptions of each Challenge, associated open access data, open source code and resultant publications can be found here.


Current Challenge

For support with the current Challenge, please contact Previous Challenges are not generally supported, but requests will be considered, and the submission of open-source code to be re-run on past Challenge data will be considered if the requestor can provide resources to assist us. Unfortunately, the funding from the NIH and our generous sponsors cannot always match the large number of requests that we receive. Test data from previous Challenges will not be released under any circumstance to prevent overfitting on the test data.

Computing in Cardiology (CinC)

For support from Computing and Cardiology (CinC), please email Although we partner with CinC, we cannot provide exceptions to the conference rules, discounts on fees, visa support letters for attendance, or other specific information about the conference not directly related to the Challenge.
