Dr Timothy Wells is a Senior Research Fellow at the Frazer Institute, The University of Queensland. Dr Wells is a molecular microbiologist whose research focuses on the interactions between the host immune system and Pseudomonas aeruginosa during chronic lung infections. Dr Wells’ research investigates antibody-dependent enhancement of bacterial infection. Dr Wells research identified patients that produced a specific antibody that protected their infecting P. aeruginosa from killing by the immune system. These ‘cloaking antibodies’ target lipopolysaccharide on the bacterial surface. Importantly, patients with these antibodies have worse lung function and outcomes then those with normal immune killing. His research uses a mixture of molecular microbiology, immunology and genomic approaches and has directly led to novel treatment of critically ill patients with multi-drug resistant bacteria.
