I am working as a Post-Doctoral Research Associate with Martin Stevens, investigating how to optimise camouflage when targets can appear in multiple different environments. I am generally interested in how humans and other animals perceive the world and how they use this information to make decisions.

Broad research specialisms

  • Visual perception
  • Behavioural ecology
  • Sensory ecology

Research interests

The broad research question that I am interested in is how humans and other animals use visual information to search and interact with the world. I have an interdisciplinary background, including aspects of biology, psychology and neuroscience, and my research therefore brings together tools and techniques from these different areas.

Previously, I worked to investigate the hypothesis of 'motion dazzle' during my PhD at the University of Cambridge. Motion dazzle is the idea that certain animal patterns may have evolved to protect an animal when in motion, by making it difficult for a predator to accurately track their speed or direction. Classically, motion dazzle has been thought to be caused by high contrast, striking geometric patterns, such as the stripes found on zebra. I found evidence for striped patterns biasing trajectory estimation in human participants. However, I found that targets with other types of low contrast patterning can also be difficult to capture, suggesting that the classical definition of motion dazzle may be too limited.

Research projects

During my research associate position at Falmouth, I will be working on a BBSRC/QinetiQ grant which will aim to try to understand how camouflage should be optimised in conditions where a target can be viewed against two or more backgrounds. I’ll be using both touch-screen games with human participants in the laboratory and also larger scale ‘citizen science’ games that will be played online.
