What do you do with Data Science?
The group has a strong focus on innovation in healthcare data science with work focusing on digital phenotyping of cardiovascular disease and the development of automated assays of care quality within the electronic health record. Key areas of investigation include (1) data science innovation that leverages structured and unstructured elements in the electronic health record (EHR) to evaluate quality of care and their association with patient outcomes, (2) applications of machine learning to achieve precision inference from clinical trials, (3) deep learning and artificial intelligence to enhance novel disease detection from wearable devices, electrocardiography, cardiac imaging, and natural language, and (4) methodological investigations focusing on improving the rigor of studies that use large datasets.
