About this study

In plain language

This study aims to build computer tools that predict blood sugar using sensor readings and information about meals, medicines, and activity. It is for adults with type 2 diabetes who get care at Johns Hopkins Medicine. The goal is to help people manage diabetes through phone apps and digital tools.

The primary objective of this research, funded by Samsung Strategic Alliance for Research and Technology, is to develop multi-modal foundation models that integrate Continuous Glucose Monitoring (CGM) data with patient behavior data (food intake, medication, and physical activity) to improve real-time glucose prediction and personalized diabetes management for patients with Type 2 diabetes (T2D), delivered via mobile apps and digital health tools.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • Be 18–75 years old with type 2 diabetes, and be a registered Johns Hopkins Medicine patient whose diabetes is managed there by a primary care doctor or hormone specialist.
  • Use an Android smartphone and a Dexcom G7 or FreeStyle Libre 3 continuous glucose monitor (CGM), a sensor that tracks blood sugar, with its matching app.
  • Have used the CGM for the 2 weeks before joining, wearing it at least half of that time.
  • Have blood sugar in the target range less than 70% of the time during the 14 days before joining.
  • Be able to read, understand, and communicate in English, and have no hearing or vision impairments.
  • Be willing to download Welldoc and Google Health Connect, plus Samsung Health if your phone is not a Samsung.
  • Agree to wear a Samsung Galaxy Watch at least 12 hours a day and use the CGM at least 80% of the time.
  • Take a photo of every meal.

Who can't join

  • Are pregnant.
  • Do not speak English.
  • Have a hearing or vision impairment.
  • Use an insulin pump, including an automated insulin delivery system.
  • Have a form of diabetes other than type 2, such as type 1, LADA, MODY, or diabetes during pregnancy.
  • Do not use an Android smartphone, such as if you use an iPhone.
  • Have CGM readings below the target blood sugar range more than 4% of the time in the 14 days before joining.
  • Were hospitalized in the past 6 months for diabetic ketoacidosis (a dangerous acid buildup linked to diabetes) or severely low blood sugar.
