Jason Tylianakis
Jason is a professor in ecology at the University of Canterbury, New Zealand (UC webpage), and Visiting Professor at Imperial College London at Silwood Park. He is the current Director of the Food Transitions 2050 Joint Postgraduate School and also a principal investigator in the Bioprotection Research Centre. His research examines how communities of interacting species (sometimes including humans) respond to environmental changes. In particular, he is interested in how the architecture of interaction networks (such as food webs or pollination networks) comes to exist, and how it responds to environmental drivers. He is also interested in the conditions under which biodiversity loss has the greatest impact on ecosystem functioning and services, and in searching for win-win scenarios to balance agricultural production and conservation. In some cases, this requires knowledge of how species traits and the local environment jointly shape the structure of interaction networks, and how this structure affects processes at the entire community level. He addresses these questions using a variety of systems (plants, insect herbivores, parasitoid-host systems, plant-mycorrhizal associations) and approaches (field observations, field and lab experiments, meta-analysis). Jason holds several service roles, including on the Science Advisory Panel to the Ministry for the Environment, and on the Board of Reviewing Editors for Science. Our group meets jointly with Daniel Stouffer's lab group at UC.

Postdocs
Hao Ran Lai 赖浩然
Hao Ran is conducting theoretical work that addresses the link between ecological and (co-)evolutionary processes at local and regional scales in the context of pests, pathogens, or weeds. He will build spatiotemporal metacommunity models to understand evolutionary and ecological trade-offs between abiotic responses and biotic interactions with enemies and resource species. He has independent project funding from the Marsden fund, and his work with us is funded by Bioprotection Aotearoa, a centre of research excellence. Find out more about him on his webpage.
