My DPhil investigated soil seed banks to assess how fungal pathogens influence the composition and diversity of propagating seedling communities through their effects on plant growth and mortality. I worked in temperate grasslands in Wytham Woods, Oxford, and also in multiple tropical forest sites across a rainfall gradient in Panama looking at the effect of altered humidity on the strength of these important plant-natural enemy interactions. I also investigated how insect seed predators influence viable seed production in tropical trees on Barro Colorado Island, Panama, with potential consequences for seedling recruitment.
In March 2016 I started a postdoc position in the group investigating the effects of climate change on host-parasitoid food webs, focusing on Australian Drosophila and their parasitoids. I left in May 2018 to take up the post of Engagement Officer at the British Ecological Society.
