Dr. Tim Barker is an internationally credentialed (INGUIDE) research methodologist and Senior Research Fellow at the University of Adelaide. He is dedicated to ensuring healthcare decision-making is informed by reliable evidence, synthesised using appropriate methodology. This methodological expertise has led to his significant influence on global and national health policy. He leads a major research partnership with the World Health Organization (WHO), where his work as Chief Investigator on insecticide-treated nets directly informed the 2024 WHO Guidelines for Malaria. This collaboration has secured over $319,000 in research funding. Dr. Barker is also frequently invited to guide evidence synthesis and recommendation development for influential national panels, including for the Royal Australian College of General Practitioners (RACGP), the Society of Obstetric Medicine of Australia and New Zealand (SOMANZ), and the University of Tasmania. He serves as a trusted expert Methodological Reviewer for the NHMRC, assessing national guidelines to ensure they meet the highest standards.Dr. Barker’s is the Deputy Director of the Adelaide GRADE Centre , Chair of the JBI Effectiveness Methodology Group, and Founder of the international RIPPER (Research Integrity and Predatory Publishing in Evidence Reviews) working group
