An expert in genomics, Ian worked for several years as an investigator for the Institute for Genomic Research in the US, where he led the sequencing of many microbial genomes. He is an ISI Highly Cited Researcher and holds a NSW Life Science Research Award at Macquarie. Ian is currently using genome sequencing, metagenomics and functional genomics to understand how lateral gene transfer in bacteria enables them to adapt to different environmental niches Research interests: Understanding microbial physiology and evolution through global approaches such as genome sequencing, metagenomics, bioinformatics, transcriptomics and proteomics.

My research interests have focused on understanding microbial physiology and evolution, by utilising "big picture" or global approaches such as genome sequencing, transcriptomics, proteomics and phenomics in combination with established molecular biology and biochemistry techniques. Visit my blogspot for updates but the themes of my research are:

Genome diversity, metagenomics and lateral gene transfer System biology analysis of membrane transport and metabolism Applying Genomics to Medicine Marine Microbiology Synthetic Biology
