We are looking for an enthusiastic PhD student interested in the ecology and evolution of warning signals, and with a passion for insects and invertebrates. The project will involve exploring potential links between dispersal, invasiveness, and anti-predator colour strategies. Background in ecology and evolution is expected. The project will involve analysing large datasets, so programming experience in R (and interest in programming) is desirable. There will be opportunity for some fieldwork as well. Location: University of Melbourne (Australia), ranked one of the best cities to live in the world. There is also opportunity to travel to Swansea University (UK) to visit co-supervisor A/Prof Will Allen, and other locations depending on fieldwork.
