Research Skills Program

The HeartShare Research Skills Program is a 1-year, full-time research fellowship intended for post-doctoral trainees interested in gaining clinical research skills in data science. The program includes an intensive 3-month bootcamp led by the Northwestern Computer Science Department in which trainees receive hands-on training in data management, programming, and application of machine learning and artificial intelligence approaches to clinical research in data science. The remaining 9 months are dedicated to completing a mentored research project related to HFpEF, using the approaches they learned in the data science bootcamp. Fellows are paired with one clinical mentor and one data science mentor and attend monthly virtual work-in-progress and career development meetings, as well as HeartShare committee meetings relevant to their proposed research project. Fellows have access to extant datasets/images and EHR data compiled for HeartShare to use for their research project and are immersed in the HeartShare research environment.
