Kim Frisch (PhD, MSc) is radiochemist and senior scientist at the Department of Nuclear Medicine and PET Centre at Aarhus University Hospital in Denmark. His obtained his degrees at the Department of Chemistry, Aarhus University: Master in organic electrochemistry and PhD in organic synthesis and asymmetric organocatalysis. Since 2009, his has been researcher in the Liver PET research group at the PET Centre. From 2013 to 2015, he also had a position of production manager at the section of Nuclear Medicine at Aarhus University Hospital. Along his career, he has visited the School of Chemistry, University of Nottingham in the UK and the Centre for Advanced Imaging, University of Queensland, St. Lucia, Brisbane in Australia. His research topic is the development of PET tracers to study liver functions. He is particularly interested in bile acids and their transport in liver and intestine, and he has developed the radiosynthesis for a series of carbon-11 labelled bile acid analogs including 11C-cholylsarcosine, which has proven useful for the quantification of conjugated bile acids transport in hepatocytes in healthy humans and in patients with cholestasis. He is an author of the book entitled Functional Molecular Imaging in Hepatology published by S Keiding and M Sørensen (Bentham eBook): Biliary secretion by K Frisch and AF Hofmann, pages 49 to 75.
