Neuroethology

Lochlan Walsh
In my PhD work, I seek to understand how animals use movement as a way of optimally extracting sensory input from environmental features, such as flower patterns, and use them to guide their behaviours. I use methods from computational ethology to track and quantify the pattern-vision-related behaviours of hummingbird hawkmoths.
My research
Drawing inspiration from an integrative biology approach, I aim to understand how organisms operate on a variety of scales - from the function of individual sensory receptors, to the physical interaction of the body with the environment. To combine these aspects in my PhD, I investigate the visuomotor control underlying flower pattern interactions in the hummingbird hawkmoth (Macroglossum stellatarum). I make use of computer vision tools such as pose estimation (e.g. DeepLabCut) to track and quantify the coordination of body parts with visual input during behaviour. My work uses this unique (and fascinating!) animal model to identify how relatively 'simple' brains can achieve precise visuomotor coordination, relating their control strategies to those seen in higher vertebrates. Additionally, using ecologically-relevant stimuli allow us to infer how such control strategies enable efficient and successful behaviour in the natural world.
