I am Professor of Catchment Science with interests in soil erosion, its downstream impacts and associated land management challenges. I specialise in development and application of environment forensic/diagnostic approaches to solve complex sediment and pollution problems from catchment to coast.

I undertake research, undergraduate and postgraduate teaching in river basin science and physical geography.

Director of the Sustainable Earth Institute.

Director of the University of Plymouth Consolidated Radioisotope Facility (CoRiF).

• Fellow of Royal Geographical Society (with the Institute of British Geographers)
• International Association for Sediment Water Science (IASWS)
• International Association of Hydrological Science (IAHS)
• British Society for Geomorphology (BSG)

Member of UN FAO/IAEA Coordinated Research Project D1.50.17 on “Nuclear Techniques for a Better Understanding of the Impact of Climate Change on Soil Erosion in Upland Agro-ecosystems”

Formerly on International Association for Sediment Water Science Board of Directors

I teach on the following subjects with a strong emphasis on linking teaching to my research: 

• Hillslope hydrology and soil erosion

• River basin fine sediment dynamics from catchment to coast 

• Environmental pollution (especially sediment quality and legacy impacts of mining) 

• Catchment science and management 

• Catchment ecosystem services 

• Geohazards: wildfire

• Geographical science methods 

Wherever possible, my class teaching of process theory is supported by field- and laboratory-based practicals e.g. rainfall simulation to explore impacts agriculture on overland flow and soil erosion or quantification of the environmental quality of streams to assess the effectiveness of catchment sensitive farming.
