Standards, methods, and guidance for evidence synthesis in environmental health
My main area of research is adaptation of systematic review methods from clinical to environmental health and toxicological contexts. I work on best practice standards for conduct of systematic reviews and the development of critical appraisal tools for assessing the quality of primary and secondary research - in particular, how such tools can be applied in manuscript production workflows to raise publishing standards.
I also working on methods for computable research, that would allow data about study methods and findings to be automatically added to research databases. This could enable a step-change in research accessibility, taking data out from behind journal paywalls, allowing automated systematic review, and enabling full access to the wealth of scientific data humans generate but now exceeds our capacity to review.
Research Themes
Evidence Mapping and Computable Research
Evidence maps are a novel evidence synthesis product which allow systematic identification of gaps and gluts in decision-critical evidence. However, they only really work if we can move our vast store of scientific information from unstructured archives of PDFs into queryable databases. This requires us to teach machines to "read" scientific documents, develop semantic authoring tools for writing scientific studies, and create comprehensive research metadata records in suitable underlying knowledge organisation systems. If we do this, we could move away from manual systematic reviews into more automated methods of synthesising evidence.
Best Practice in Systematic Review
I work on developing and promoting best practice standards for conduct of systematic reviews and evidence maps in the environmental health sciences. This mainly involves adapting existing standards in use in biomedical research to the toxicology and environmental health context. The idea is that, if we can provide environmental health researchers with an authoritative recipe-book for conducting systematic reviews, it should help them reduce the risk of conducting unsuccessful SR projects.
Critical Appraisal Guidance and Instruments
While there are a lot of critical appraisal tools for helping people distinguish more credible studies from less, it is not always clear which tool should be used and when, nor if any given tool is actually fit-for-purpose. I am working on or contributing to several tools for critically appraising systematic reviews and primary studies, concentrating on ensuring they target an appropriate quality construct for the context in which they are to be used, that are reasonably intuitive, and they reliably distinguish higher-quality from lower-quality research.
