Sustaining the Biomedical Research Workforce: Medical School Leadership in Supporting Research Learners.

Biomedical graduate students and postdoctoral researchers contribute to scientific innovation, driving discovery and advancing health solutions. However, their success depends on more than research skills; they require strong mentorship, mental health support, and inclusive training environments. Despite the critical importance of research learners, the current structures at many medical schools prioritize clinical learners, often leaving research learners without adequate institutional support. Unique challenges, including prolonged training, reliance on a single mentor, and dual roles as learners and researchers, are compounded by high stress, ineffective mentorship, and underaddressed mistreatment, particularly for underrepresented groups. This commentary highlights the urgent need for medical schools to address these issues through targeted interventions. Institutions must implement proactive mental health strategies, strengthen culturally aware and effective mentorship, and foster inclusive research environments that promote equity and psychological safety. By prioritizing these efforts, medical schools can support research learners' success, reduce attrition, and cultivate a diverse and innovative biomedical research workforce. This approach is an investment in the future of biomedical research and its long-term sustainability.
