A question often asked of those of us who work in the seemingly esoteric field of fish vision is, why? To some of us the answer seems obvious – how many other visual scientists get to dive in a tropical lagoon in the name of science and then are able to eat their subjects for dinner? However, there are better, or at least scientifically more acceptable, reasons for working on the visual system of fish. – Douglas & Djamgoz, 1990

Valerio is a visiting MSc student from the Swiss Federal Institute of Technology in Zurich (ETHZ), Switzerland. Originally from the swiss-italian side of Switzerland, he moved to to french region to complete a bachelor in Biology at the University of Lausanne. He grew up in the middle of the Alps, but always had a fascination for marine life, which brought him to undergo his Master’s thesis here at the Sensory Neurobiology group on the visual system of surgeonfish, under the supervision of Dr Fanny de Busserolles and Dr Fabio Cortesi.


I’m interested in marine biology as a whole, genetics, evolution, and visual ecology. I like to tackle questions with different approaches and research techniques. I’m currently investigating different life stages of the spotted unicornfish visual system through retinal mapping, and next generation RNA sequencing. I’m also researching the evolution of opsins genes in Surgeonfishes and its ecological context, defined by habitat and feeding behaviour.
