Professor Oliver Rackham
Profile
Professor Rackham’s team focuses on using synthetic biology to engineer and understand transcriptomes, the genetic code, genomes, and organelles. Oliver established his own group at the Perkins in 2006 as an National Health and Medical Research Council (NHMRC) Peter Doherty Fellow. Since then he has been awarded a Wenner-Gren Foundation Fellowship, an ARC Future Fellowship, the Marshall Medal, and was inducted into the European Inventor Hall of Fame. He was a founding member and past President of Synthetic Biology Australasia. Oliver is currently an NHMRC Senior Research Fellow and Node and Theme Leader of the ARC Centre of Excellence in Synthetic Biology.
Research Overview
Professor Rackham‘s research falls into two areas of interest: engineering and understanding mammalian gene expression, and synthetic biology. His work focuses on developing new tools and therapeutics to target cancer, mitochondrial diseases and antibiotic-resistant bacteria.
Research Projects
Synthetic Biology
One of the key aims of synthetic biology is to program cells with new functions. To achieve this aim it is necessary to create additional, new components that interact in a programmable manner, both with each other and with the existing cellular network. To engineer these components we have created a number of powerful new genetic selection approaches that can be used to tailor the molecular specificities of genes, RNAs and proteins in bacteria and yeast. Current projects involve developing new and improved gene editing systems and engineering cells to produce new antibiotics.
Mammalian Gene Expression
From synthesis to destruction, mRNAs are associated with an array of proteins. Proteins control the efficiency of transcription, processing, nuclear export, translation, localization and degradation of mRNA. The importance of regulation at the level of mRNA has become increasingly apparent with the discovery of disease causing defects in these processes. We are using synthetic biology and transcriptomic approaches to engineer and understand mammalian RNA-binding proteins for use as tools in biotechnology and as therapeutics for human diseases.
