Susan Keiding (MD, PhD) is Associate Professor at the Aarhus University (Denmark), Honorary Professor at the Copenhagen University and director of the Liver PET Research group at the University Hospital of Aarhus. She is also consultant physician at the Department of Hepatology and Gastroenterology and at the PET Centre (University Hospital of Aarhus, Denmark).

She obtained her specialisation in Medical Gastroenterology, Hepatology, and Internal Medicine and her PhD thesis on "Galactose elimination in intact pig liver". She is responsible for postdoctoral scientific training in Physiology, Biochemistry, Biophysics, Mathematics, Statistics, Experimental and Clinical Hepatology at the University of Copenhagen (Denmark). Along her carrier, she visited the Department of Mathematics at Queensland University (Brisbane, Australia), the department of Hepatology at Mayo Clinic (Minnesota, USA), Liver Transplantation Unit at Gröningen University Hospital (The Netherlands) and Liver Unit at University of California (San Francisco, USA). Visiting periods lasted between 1 to 12 months.

She published 150 original and review articles in peer-refereed scientific journals and 53 book chapters, editorials, letter-to-the Editor and articles in Danish. She is Editor of the e-book entitled  "Functional Molecular Imaging in Hepatology" (Bentham Science Publishers) published in 2012. She is a regular reviewer for Hepatology, Gastroenterology, Journal of Hepatology, Journal of Nuclear Molecular Imaging, Journal of Cerebral Blood Flow and Metabolism, European Journal of Nuclear Medicine and Molecular Imaging, Journal of Theoretical Biology, Scandinavian Journal of Gastroenterology. In total, she supervised more than 30 PhD students and young researchers.
