Our research focuses on the evolution of symbiotic associations between animals and microbes. We utilize a cross-disciplinary approach incorporating genetic, behavioral, and microbiological approaches. Work in the lab takes advantage of genomic, molecular and phylogenetic techniques to examine how microbes shape the biology of higher organisms.
Our main study system is the association between fungus-growing ants, their fungal cultivars, mutualistic bacteria, and specialized garden pathogens. We are currently sequencing the genomes of players in this system to address questions concerning the evolution of antibiotic resistance, cooperation, and social insect castes. The lab also investigates the evolution of symbiosis in additional systems including a bark beetles, honey bees, and fungus-growing termites.
The Currie lab is also involved in bioprospecting to discover new species and enzymes that will improve biofuel production. We do this by applying metagenomics, bioinformatics, microbiological techniques and metabolic assays to environmental samples, including the ants’ fungal-gardens and dumps.
Students and postdocs in the Currie lab focus on a variety of projects including microbial ecology & biogeography, population genetics & geographic mosaic theory of coevolution, bioinformatics, the evolution of antibiotic resistance and the genetic basis of symbiosis.
