Watch Professor Ian Maddock's video biography
Professor Ian Maddock joined Worcester in 1993 and has teaching and research interests in River Science, Hydromorphology, Hydroecology / Ecohydrology, Ecohydraulics, River Restoration and Aquatic Habitat Measurement, Mapping and Modelling. Ian developed and is the leader of the University’s River Science Research Group.
The primary focus of his research is on developing methods for measuring, mapping and monitoring the hydromorphology of streams and how this influences habitat hydraulics. Ian often works collaboratively with river scientists in multidisciplinary teams, especially with ecologists and biologists to develop sustainable solutions to river management and water resource issues. Ian also has a research interest in the use of Drones or Unmanned Aerial Vehicles (UAVs) and Terrestrial Laser Scanners (TLS) for ultra-high resolution remote sensing of river morphology and measurement of river velocity and river discharge. He has had a UK Civil Aviation Authority approved Remote Pilot Qualification small (RPQ-s) and has managed the School of Science and the Environments Permission for Commercial Operation since 2011, including updating his pilot competency with additional ground school training to maintain currency in 2016. Ian has flown the University's drones for research in the UK, Chile, Switzerland and Slovenia.
Ian has developed an externally-funded research program that has generated field experience and publication based on work in the UK and internationally, having conducted research and consultancy in Australia, Slovenia, Chile, Ireland and the USA. He has provided research and scientific policy support to government organisations (e.g. Environment Agency), research institutions (e.g. Centre for Ecology and Hydrology), research councils (e.g. NERC) and environmental consultancies (e.g. ENTEC UK, CDM Ireland) and has a range of publications in international refereed journals and edited book chapters. He supervises numerous PhD students and MRes in River Science students (see below) and has a 100% track record for successful completions of his PhD students.
His University learning and teaching experience includes being a tutor for BSc Geography, BSc Physical Geography and BSc Environmental Science degrees and he led the development of and is course leader for the MRes in River Science. He has been leading on the development of using drones for environmental monitoring, topographic surveying and geomorphic change detection in the Geography and Environmental Science curriculum and has enhanced undergraduate skills through the use of real-time telemetry at UW river monitoring sites for flow and water quality monitoring. He has also collaborated on the development of virtual fieldwork with Dr Des McDougall.
