Associate lecturer (ATER: Teaching and Research Temporary Attaché)



I am a marine ecologist, interested in examining the natural and human-mediated processes affecting the diversity, structure, functioning and evolution of marine communities (from multiple habitats). My expertise encompasses various fields, especially taxonomy, sampling design, data analyses and ecological theories. In recent years, my research has been focussed on the influence of anthropogenic activities (ocean sprawl) and biotic processes on species invasions and biodiversity loss at multiple spatial scales.
