The grant is the largest awarded in the UK to study the microbiology of the lung infection.
The US-Ireland collaboration also involves researchers from Dublin and North Carolina.
Professor Stuart Elborn from Queens said the aim is to discover the role of bacteria known as anaerobes in causing damage to the lungs of people with the illness.
"The results of the study will be of important clinical relevance to people with cystic fibrosis because, if we show that these anaerobes are contributing to infection and inflammation in the lungs of cystic fibrosis patients, in the future patients could potentially be given more appropriate and effective antibiotics which should improve their clinical outcome and quality of life," he said.
The project has been funded by the US-Ireland Research and Development Partnership.
It will also examine whether the bacteria are able to produce chemicals that can damage lung tissue and break down antibiotics given to treat lung infection as well as considering how effective different antibiotics are in treating them.
