I study the evolution and ecology of animal coloration focusing particularly on mammals and decapods. I conduct fieldwork in Tanzania and UK on zebras and horses, on coconut crabs on the Zanzibar archipelago, and on crabs and anemones in UK. My work is highly collaborative involving phylogenetic macroevolutionary comparative studies, simple field experiments, and state-of-the-art photographic techniques to test classic hypotheses about coloration of often charismatic conspicuous species.

I am also interested conservation strategies used to sustain intact tropical ecosystems, and , more practically, I work in collaboration with Tanzanian authoriies on a number of conservation projects in that highly biodiverse country.
