Katharina Gaus (12 July 1972 – 3 March 2021)[3] was a German-Australian immunologist and molecular microscopist. She was an NHMRC Senior Research Fellow[4] and founding head of the Cellular Membrane Biology Lab, part of the Centre for Vascular Research at the University of New South Wales.[5] Gaus used new super-resolution fluorescence microscopes[6][7][8] to examine the plasma membrane within intact living cells, and study cell signalling at the level of single molecules to better understand how cells "make decisions".[9] A key discovery of Gaus and her team was how T-cells decide to switch on the body's immune system to attack diseases.[10][11] Her work is of importance to the development of drugs that can work with T-cells in support of the immune system.[9]
As of 2005, Gaus founded the Cellular Membrane Biology Lab, part of the Centre for Vascular Research at the University of New South Wales.[12][13] As of 2009 she became a senior research fellow and associate professor of the National Health and Medical Research Council (NHMRC) in Australia.[13]
Gaus was a member of the Australian Centre for NanoMedicine, founded in 2011, which is based at the University of New South Wales.[15] She was also deputy director and a chief investigator of the ARC Centre of Excellence in Advanced Molecular Imaging.[16]
Gaus was active in encouraging girls to enter scientific fields.[17]
