My research aims to answer this fundamental question; how does genome architecture influence an organism’s ability to respond to, and more importantly adapt to, its environment. In its simplest form, this means examining chromatin based mechanisms of gene expression regulation. On evolutionary time scales, it involves asking whether changes to chromatin architecture can dictate evolutionary trajectories.
We use single celled yeast species from the Saccharomycotina subphylum to answer these questions, which includes the model organism Saccharomyces cerevisiae and the pathogenic yeasts Candida spp. species.
The three distinct approaches we use in the lab are:
- Experimental evolution of S. cerevisiae to determine how changes in histone proteins, the building blocks of eukaryotic chromatin, influences the ability of this yeast to adapt to novel environments.
- Reverse genetics (CRISPR-Cas9) of the human pathogen Candida glabrata to ascertain the contribution of histone modification pathways to the emergence of virulent traits in this species, including phenotypic plasticity and anti-fungal resistance. (Figure 1)
- Comparative epigenomics of Candida spp. to probe the conservation of histone modification marks between human fungal pathogens.
The lab is currently accepting PhD applications in the field of antifungal resistance & tolerance.
