Dr Holger Unger is a staff specialist in obstetrics and gynaecology at the Royal Darwin Hospital. He is a Senior Research Fellow at Menzies School of Health Research and a Honorary Academic Clinical Lecturer at the Liverpool School of Tropical Medicine, Liverpool, UK.
His research focuses on the prevention of Plasmodium falciparum and Plasmodium vivax infections during pregnancy and the puerperium in the Asia-Pacific region. He supervised a clinical trial of intermittent preventive treatment in pregnancy in Papua New Guinea, and conducts research into the interplay between undernutrition, inflammation, malaria and other infections during pregnancy and their impact on adverse pregnancy outcomes. His portfolio includes clinical and epidemiological studies, biomarker research, data linkage studies, individual participant data meta-analyses, and qualitative research.
Additional research interests are preconception care, preterm birth, and the management of the second-stage of labour in low-resource and remote settings.
Dr Unger co-ordinates research activities at the Department of Obstetrics and Gynaecology at the Royal Darwin Hospital, and initiated the establishment of a Women’s Health Research Group at Menzies School of Health Research.
