My research focuses on ecological genomics and processes related to diversity maintenance in tropical forests. Specifically, I am interested in conspecific negative density dependence (CNDD), and how this process influences local relative abundance of tropical tree species. Fungi are recognized as important drivers of CNDD, but the fungal communities associating with tropical trees remain poorly understood. I am conducting experiments using metabarcoding approaches to identify components of root associated fungal communities associated with CNDD strength.
I am also pursuing a project that utilizes pooled whole genome sequencing to identify genes associated with flight metabolic rate (FMR) in Edith’s Checkerspot butterfly. In a related species, genes associated with FMR have been shown to be important in driving metapopulation dynamics. Understanding these genes may facilitate successful reintroductions of endangered subspecies of Edith’s Checkerspot.
