Team Soleil

Population Health Research Program in Heart Failure and Cardiovascular Interventions (Team Soleil)

Team Soleil’s research program is based on heart failure and long-term outcomes after cardiovascular interventions. The scope of work encompasses precision medicine, sex and gender epidemiology, as well as patient-oriented outcomes.

Specific projects include personalized perioperative and long-term risk prediction, biomarker discovery, and population-based epidemiology studies that aim to improve the outcomes of medical and surgical patients with cardiovascular diseases, finding innovative solutions for disparities and improving access to care. This is accomplished through applying machine learning and advanced statistical techniques on integrated population- and precision-based datasets. The team also specializes in the development of digital health applications and medical devices that are directly relevant to patient care and clinical operations.
