Wiebke’s research focus is the exploration of the role of steroid synthesis and metabolism in human health and disease. Her work has identified the key role of adrenal androgens in women, establishing DHEA replacement in women with adrenal insufficiency (N Engl J Med 1999). She has discovered the molecular basis of novel androgen excess disorders (POR deficiency, Lancet 2004; PAPSS2 deficiency, N Engl J Med 2009), leading to new insights into pathways of human androgen synthesis and metabolism. As a Wellcome Trust Investigator, she applies an integrated systems medicine approach to the dissection of androgen excess and metabolic dysfunction in the context of polycystic ovary syndrome (PCOS). To this end, she combines state-of-the-art human in vivo physiology, innovative ex vivo and in vitro approaches and the exploration of the steroid and global metabolome by machine learning-based computational tools. Her group also applies this steroid metabolomics approach, the combination of mass spectrometry-based steroid profiling with machine learning-based data analysis, to the delineation of steroid excess and metabolic impact in the context of endocrine hypertension and adrenal tumours. Wiebke leads the Dissecting Androgen excess and metabolic dysfunction – an Integrated Systems approach to PolyCystic Ovary Syndrome (Daisy PCOS) Research Project. It's a new research study which examines the metabolic nature of PCOS and its links to other health conditions.
