Professor Lars Nielsen leads the development of experimental and computational tools to analyse and design complex biological systems. His expertise in metabolic modelling and flux analysis is available nowhere else in Australia – and in few labs across the world. Professor Nielsen’s studies of biological systems as diverse as bacteria, baker's yeast, sugarcane, insects and mammals has attracted industrial partnerships with companies including Dow, Metabolix, Amyris, LanzaTech, Boeing, Virgin Australia and GE. These metabolic engineering partnerships have focussed on developing new ways of producing aviation fuel, various materials and bioactives (antibiotics, biopesticides, monoclonal antibodies). Professor Nielsen is also applying system analysis and design approaches to tissue engineering including novel strategies for generating microtissues for drug screening and using stem cells to produce red and white blood cells for transfusion.
