Research Interests

The Waksman laboratory at CIMR works on investigating bacterial conjugation. Bacterial conjugation is the principal means by which antibiotic resistance genes spread among bacterial populations. Antibiotic resistance constitutes a major threat to public health systems worldwide. It is therefore biomedically important that we gain a detailed understanding of the molecular mechanism by which genes are transferred from one bacterium to another.

Major Contributions

1. First characterisation of the biogenesis mechanism of extracellular appendages involved in host-pathogen recognition (Science, 1999; Cell, 2001; Cell, 2002; Cell, 2008; Nature, 2011; Nature, 2013; Cell, 2016a).

2. First insights into the mechanism of inter-bacterial gene transfer during bacterial conjugation (Science, 2009; Nature, 2009; Nature, 2014; Cell, 2016b; Cell, 2017; Nature, 2022).
