10 PFI Fellows per year are chosen through a competitive application process. They work in teams to solve data-focused problems for a chosen thematic area. Because of the importance of interdisciplinary exposure and problem-focused nature of our training, these fellows will come from a range of STEM and non-STEM disciplines. A limited number of fellowships (at most 3 per year) are offered to graduate students specializing in data science or computer science, to bring their methodological perspectives into the Interdisciplinary Immersion Program. T-TRIPODS institute, focused on the Foundations of Data Science, will assist in finding and evaluating these applications. Ten $3000 PFI Fellowships per year are available.
