About Gudmundur Johannsson
Major research interests include pituitary diseases, the importance of growth hormone in adults and adrenal insufficiency. I have established three research tracks focusing on improved endocrine replacement therapies, specifically growth hormone and glucocorticoids, and prediction of pituitary tumour growth. The focus is currently on biomarker discovery within endocrinology. I have developed methodologies with unique patient populations combined with specific study designs using a translation approach with close collaboration with colleges with skills in multi-modality hypothesis-free biomarker discovery platforms.
