If you use a Fitbit or Apple Watch or other similar device to monitor your exercise, diet, or sleep routines, then you already know that those devices generate a lot of data about the state of your health, including weight/body fat percentage, heart rate, blood pressure, and sleep quality. But who owns that data? You? The manufacturer of the device? What about your employer, if you are a pro-athlete, for example? This is precisely the question that my colleagues John Holden and Kimberly Houser pose in their work in progress “Data Trusts, Betting & Biometrics” — my favorite (thus far) paper of the yearly ALSB  conference that I have been attending this week. #ALSB2020
