What we do

Our research is centered on the ecology and evolution of opportunistic pathogens, the genes involved in virulence, competition, transfer of genetic material and antibiotic resistance, and the factors that support interactions between bacteria in microbiomes. The aim of our research is to combine data-driven bioinformatic approaches with high-throughput molecular methods and the robust theories developed for plant and animal ecology to understand pathogens, microbial communities and their interactions, in order to improve human and environmental health. We mainly do work in three areas associated with this overarching goal: i) the mechanisms behind pathogenicity, ii) the effects of disrupted interactions in microbiomes, and iii) the development and spread of antibiotic resistance. In addition, the lab develops tools for large-scale bioinformatic analysis of high-throughput data, including the widely used ITSx and Metaxa software, to support cutting-edge research in these three areas. We also maintain a strong interest in maintaining and improving accuracy and reliability of sequence databases.
