Researcher biography
Dr Timothy Wells joined the Diamantina Institute in 2016 as a Senior Research Fellow. His research focuses on the interactions between the host immune system and Gram negative bacteria during chronic lung infection. Dr Wells is passionate about making his research as clinically relevant as possible, with his work previously having led to novel treatment of critically ill patients. His research uses a mixture of molecular microbiology, immunology and genomic approaches.
