Research interests

Using GPS telemetry data and acoustic propagation modelling, I aim to understand the exposure and behavioural response of grey seals (Halichoerus grypus) to shipping noise. Shipping is a primary source of underwater noise in the ocean and increasingly evidence suggests it can have a detrimental impact on marine life. Grey seals can perceive sound at the same low frequency range emitted by ships and the UK is home to a substantial grey seal population, a protected species under the EU Habitats Directive. However, the UK is also surrounded by some of the world's busiest shipping lanes. Supervised by Dr Clare Embling, Professor Georgy Shapiro, Dr Simon Ingram and Dr Feng Chen, my research aims to improve our understanding of shipping noise and its impacts on grey seals in order to inform effective marine planning and conservation.

Other research

Previous research projects include:

  • Assessment of acoustic indices for monitoring phylogenetic and temporal patterns of biodiversity in tropical forests.
  • Using tri-axial accelerometers and behavioural observation to measure the performance of horses ridden in single-jointed and straight bar snaffle.
