Hi! I I currently hold joint positions at the University of Liverpool, and the Max Planck Institute for Chemical Ecology, where I head Research Group Predators and Toxic Prey.

Previously, I was a Lecturer and a Junior Research Fellow at the University of Cambridge. Before that, I completed my PhD at the University of Liverpool. I have worked on a range of systems to study the evolutionary interactions between predators and prey that are orchestrated by the chemistry of plants and that are entangled with evolved abilities of prey and predators to overcome defence compounds.

I integrate research across different biological levels of organization, using tools from small molecule chemistry, physiology, molecular and cell biology, and behavioural ecology to address the fundamental questions: 1) how do new traits arise and become established in populations? 2) How do traits vary across levels, i.e., among individuals within populations, and among populations? And 3) what are the factors that promote and maintain trait variability?
