Research in the lab headed by Grant Hughes centres around host-microbe interactions within mosquitoes and understanding the molecular basis for these interactions. Specifically, we are interested in the following topics.
- Examining the tripartite interactions between mosquitoes, their microbiome and the pathogens they transmit.
- Characterising transmission routes of gut associated microbes within mosquitoes.
- Developing new tools for manipulating microbiota and identifying mosquito phenotypes influenced by the microbiome and the genetics that mediate these interactions.
- Exploiting gut associated microbes to deliver molecules to interfere with pathogen transmission in mosquitoes.
- Developing novel tools to engineer mosquitoes.
- Exploiting genetics approaches to render mosquitoes incapable of transmitting pathogens to humans.
