Personal profile


I joined Macquarie University’s Department of Biological Sciences in July 2018. I am an evolutionary biologist and molecular ecologist. My background is in botany, microbiology, population genetics, and phylogeography. My research is focused under three broad themes: the population dynamics of invasive species, plant evolutionary biology and biogeography, and plant-microbial interactions. I am specifically interested in understanding aspects related to the phylogeography and population genetic structure and diversity of invasive plants, extreme long-distance dispersal in explaining historically disjunct distributions, the dynamics of plant-bacterial interaction networks, soil microbial community diversity and functional responses to plant community compositional changes, and plant evolutionary biology.
