Personal profile


Research Expertise and Interests

Dr Tory Milner is a Senior Lecturer in Physical Geography, who specialises in ecohydrology, river science, fluvial geomorphology, extreme hydrological events and community ecology. Tory joined the University of Huddersfield in April 2019, after previously working at the University of Worcester. Her research and teaching interests are in:

  • The interactions between riverbed morphology and invertebrate communities in natural settings.
  • The effects of anthropogenic activities (i.e. flow regulation, influxes of fine sediment) on physical habitat heterogeneity and benthic invertebrates.
  • The influence of streambed drying on flow intermittence gradients and aquatic biota.

Ongoing research projects include 1) examining whether pebble clusters provide a refuge for invertebrates during flood disturbances in mixed bedrock alluvial streams, 2) identifying the impact of fine sediment on bed substrate characteristics and the behavioural response of invertebrates, and 3) investigating the biodiversity and community composition in intermittent rivers.
