He has been studying the liver sinusoid since 1990, and the effects of ageing on liver sinusoidal endothelial cell (LSEC) morphology and scavenger function. His lab is particularly interested in the use of super-resolution optical microscopy (SIM and dSTORM) to resolve LSEC structures below the 250nm optical diffraction limit. He is currently (2016-17) on sabbatical at the Cogger/Le Couteur Biogerontology Group at the ANZAC Medical Research Institute. He is funded by the Tromsø Research Foundation, the North Norwegian Health Commission (HelseNord) and the EU Horizon 2020 program.
