Research Interests

My interdisciplinary research investigates how animals are able to use vibrations through materials and along surfaces for information. Studying this form of information transfer requires an understanding of the generation, propagation and detection of vibrations. Please see recent review published in Animal Behaviour for more information. I draw on my biological materials research background, and have projects spanning biomechanics, animal behaviour, sensory ecology and the development of new monitoring technologies.

Current projects include investigating how spider webs influence vibration propagation, and how spiders can use this information to determine the location of vibration sources. I also investigate elephants in the field in Kenya and am a National Geographic Explorer. I look at the role that the terrain plays in the propagation distance of elephant generated vibrations and how seismic vibrations can be used to determine elephant behaviour. Furthermore, I investigate vibration sensing in the model species of nematode worm, C. elegans and vibration generation mechanisms in hemipteran bugs. I use a range of experimental approaches, including laser vibrometery, geophone arrays, vibration playback, time-resolved synchtrotron X-ray microtomography, and high-speed photography to investigate how animals use vibrations as an information source.
