Research interests

Plant and seed ecology are my main research focus. I am particularly interested in fire ecology and the ability of plants to regenerate post-fire. One mechanism that allows for this is seed dormancy, which is also a research focus of mine.

I am also interested in the analysis of seed germination data, and finding ways that this can be applied to conservation of plant species.

Current projects
