Matt teaching reflects his research experience, being focused on river processes and management. Matt's modules include field trips to rivers across the UK, where students can engage with management practitioners and projects, as well as undertaking more fundamental work, performing experiments in laboratory flume facilities.

Matt convenes and lectures:

  • River Processes and Dynamics (2nd year - GEOG2008)
  • Freshwater Management (3rd year - GEOG3015)

Matt also supervises undergraduate and Masters dissertation students researching river processes and management.

Current Research

Matt is a fluvial geomorphologist with an interest in how aquatic organisms occupy, utilise and modify environments. He works at the interface of hydrology, geomorphology and ecology is currently working on projects focused on:

1) The ability of animals to alter physical processes, such as sediment transport, in rivers.

Living organisms can alter environments through their presence and activity, with implications for geomorphic and biochemical processes. Matt is interested in how invertebrate animals alter the flow of material through river systems, including the destabilisation of river beds and banks by the invasive signal crayfish (e.g. Article Link), which can also increase the transport of sediment through rivers (e.g.link). Organisms can also stabilise river substrates (e.g. Article Link) and alter the dynamics of sediment grains (e.g. Article Link).

2) The impacts of environmental change and pollution on aquatic ecosystems.

Matt is researching pollutants in rivers, including the bioaccumulation of heavy metals in freshwater organisms, the presence of microplastics in rivers (e.g. Article Link) and the complex role of litter (e.g. Article Link). Matt is particularly concerned with the sub-lethal impacts of pollutants on invertebrate organisms across multiple life stages (e.g Article Link). Matt is also working on changing water temperature in rivers and how to increase resilience to future warming (e.g. Article Link).

3) Incorporating biological processes into river management frameworks.

Matt is keen that his work retains an applied angle and works with multiple stakeholders. He has projects in the USA and UK on river management schemes, which aim to better account for ecological processes in river management, for example (e.g. Article Link)
