Welcome! This is the research group for invasion and freshwater ecology at Newcastle University We focus on the interaction of invasive alien species and the environment on biodiversity and livelihoods (food and water security). If you are interested in joining the group, please contact me for potential opportunities.

Ava Waine

PhD student

The risks to water security from invasive by non-native species via bulk water tranfer.

Supervisors: Prof. Pete Robertson, Dr Zarah Pattison, Dr Aileen Mill, Claire Gowdy (Northumbrian Water) and Dr Martin Crapper (Northumbria University)

Email me: Starting in October 2020

Emily Hickenbotham
