In recent years, there have been increasing calls for the development and growth of the biosocial as a paradigm through which to tackle complex problems. The use of birth cohorts, mixed methods frameworks, and interdisciplinary work are common in biosocial research. However, these practices are also theoretically and practically complex due to epistemic, methodological, and academic challenges – particularly for early career researchers (ECRs) who face time constraints, funding limitations, and disciplinary expectations.

This paper draws on lessons from the experiences of ECRs in biosocial research by reflecting on theoretical heterogeneity, the necessity of translation and negotiation across disciplines and methodologies, and the practicalities of funding, collaboration, and dissemination. Throughout, the paper discusses strategies to overcome common challenges and provide suggestions for fellow ECRs and those interested in biosocial ECR training and development. The paper highlights the importance of strong networks with senior biosocial researchers and peers, the value of practical support, and the importance of formal and informal learning opportunities. The authors call for the enthusiasm for biosocial research to be matched with investment in the development and support for ECRs.
