Research Reproducibility, Open Science Policy & Metascience

As a dedicated metascience researcher and advocate for research integrity, my work examines the systemic architectures of scientific publishing, peer review, and transparency.

Supported by an ESRC Postdoctoral Fellowship (£126,071), this line of inquiry focuses on diagnosing challenges to reproducibility in the behavioral and health sciences and developing structural, community-driven solutions.

From analyzing the development and future of the Registered Reports publishing model to evaluating post-publication critique policies across top-tier disciplines, this research aims to mitigate publication bias and foster a more open, credible, and collaborative scientific ecosystem. I have also encouraged research producibility in collaborative pedagogy settings (read more about it here).
