Professor Nicholas Roberts

Nick is a Professor of Sensory Ecology in the School of Biological Sciences and is currently the Deputy Head of the Department and the Director of Research. His research concerns many aspects of visual ecology, animal vision and signalling. He is particularly interested in discovering new optical principles that animals exploit and how these influence visually guided behaviour.  The lab has pioneered and uses many novel optical and behavioural techniques.

Dr Martin How

Martin is a Royal Society University Research Fellow and holds a proleptic lectureship. His research focuses predominately on the visual ecology of marine and intertidal organisms. Specifically, he studies the detection of polarized light in mantis shrimps and fiddler crabs, colour vision in crustaceans and skin camouflage patterns in a variety of species, including nudibranchs, cuttlefish and zebra.


Research Fellows

Dr Michael Bok

Michael is a BBSRC Future Leaders Fellow.  He is interested in the unusual visual systems of a variety of marine invertebrates ranging from the rudimentary compound ocelli of fan worms to the spectacularly sophisticated eyes of mantis shrimp.  His current work on fan worms aims to unravel the developmental, neurological and behavioral factors that drove the evolution of these simple eyes and perhaps also influenced the origins of nature’s very first visual systems. 


Postdoctoral Researchers

Dr Ilse Daly

Ilse is a post-doctoral research associate funded by AFRL. Her PhD research focused on the eye movements of stomatopod crustaceans, using a custom stereo eye tracking method she studies how the bizarre eyes of the mantis shrimp respond to various environmental stimuli. 

PhD Students


Emelie Brodrick

Emelie is a PhD student funded by the Royal Society. She is researching the intricacies of how the eyes of crustaceans such as Fiddler crabs, deal with rapidly changing light environments and how this may affect their sensitivity to polarized light. Her project uses a range of study techniques, from micro-anatomical studies to behavioural experiments in the animal’s natural environmentEmelie is supervised by Dr Martin How & Dr Nicholas Roberts.


Sam Smithers

Sam is a PhD student funded by the University of Bristol and DSTL. His research concerns how and why crustaceans see the polarization of light. Using behavioural experiments, Sam is studying polarization vision in shore crabs, fiddler crabs and mantis shrimp. He is supervised by Dr Nicholas Roberts & Dr Martin How.


Alex Tibbs

Alex is a PhD student funded by the EPSRC Doctoral Training Centre in Communications. Placed jointly between the Visual Information lab in Engineering and the Ecology of Vision lab he is studying image processing for polarization cameras. Taking inspiration from animal vision, he is researching how best to exploit polarization in man-made camera systems. He is supervised by Prof Dave Bull & Dr Nicholas Roberts.


Jim Galloway

Jim is a BBSRC funded PhD student jointly supervised by Martin Stevens at Exeter and Nick Roberts. 

Jim is studying links between animal vision and colour change for camouflage.  The aim is to understand how colour change is affected by changes in light conditions and visual background.

Research Assistant

Rochelle Meah

Rochelle is a research assistant funded by AFRL. Her research focuses on polarization vision in horse and stable flies. Using behavioural experiments she will study the visual sensitivity of the biting flies to polarized light and quantify the polarization information available in their natural habitat. 


Ally Irwin

Ally is a currently a research assistant working in the lab studying contrast vision in crabs and the dazzle effect of zebra stripes.


Honorary Research Fellows


Dr David Wilby

David is now an honorary research fellow in the group. After finishing his post-doc woking on polarization vision in fish,  he's now taken up a new post-doc working with Emily Baird in Lund, Sweden.


Dr Shelby Temple

Shelby is an honorary research fellow, maintaining links with the group after leaving to set up AzulOptics and develop the commercial potential of research. Shelby has been interested in polarization perception in cephalopods, fish and humans and is currently working on commercializing a polarization-based tool for measuring macular pigment density in the human retina. Shelby recently won the 2017 UK Innovator of the Year Award by the UK Biotechnology and Biological Sciences Research Council (BBSRC).
