Biography I specialise in the spatial ecology of freshwater and diadromous fishes in a range of aquatic environments using telemetry, sonar and eDNA techniques at the University of Hull (Hull International Fisheries Institute; HIFI).

I predominantly study the impact of anthropogenic activities on fish migration, including low head weirs, fish passage solutions, pumping stations, hydropower schemes and reservoir compensation flow releases. For example, I lead the REsearch and Development of fish and Eel Entrainment Mitigation at pumping stations (REDEEM) project, investigating the spatial distribution of fish and eels in pumped catchments, the processes that lead to entrainment, the effectiveness of existing technologies and develop innovative approaches to minimise entrainment and provide safe downstream passage.

I have also led investigations into catchment-wide migration of upstream-migrating adult sea lamprey and river lamprey, twaite shad, salmonids and cyprinids.

Research Interests Internally at the University, I served on the University Research Committee (2017-2022). Externally, I represented the UK on a EU European Cooperation in Science and Technology (COST) action for the development of the European Tracking Network and England in developing a European Committee for Standardization (CEN) standards for fish pass assessment (BS EN 17233:2021). I sit on the FishPass project (hosted by Great Lakes Fishery Commission) Advisory Board – Science Team, and also a member of the Fish Passage Conference steering committee.
