Expanding pathways to clinical and translational research training with stackable microcredentials: A pilot study.

Introduction: The proportion of physician-investigators involved in biomedical research is shrinking even as the need for high-quality, interdisciplinary research is growing. Building the physician-investigator workforce is thus a pressing concern. Flexible, "light-weight" training modalities can help busy physician-investigators prepare for key stages of the research life cycle and personalize their learning to their own needs.
