Peter Melville-Shreeve

Peter Melville-Shreeve

Dr Peter Melville-Shreeve has worked in consultancy, startups and academic roles over the last decade. He works closely with the Chartered Institution of Water and Environmental Management’s (CIWEM’s) policy team to support sustainable water management systems and chair’s CIWEM’s Water Reuse Task & Finishing Group. Much of Peter’s early research focusses on rainwater management systems and the need for dual purpose designs – which can mitigate droughts and floods. His thesis highlighted the opportunities for Internet of Things technologies to be harnessed to reduce water demand AND manage stormwater flood risk. He consequently founded and exited a technology business which developed analytics and control systems to enable such technologies to be implemented at a range of scales.

Gabriel Yvon-Durocher

Gabriel Yvon-Durocher

Gabriel researches the effects of environmental change on the structure and functioning of ecosystems (which comprise groups of species, their interactions with one another and with the physical and chemical environment in which they exist). His work spans multiple levels of biological organisation, from sub-cellular biochemistry to the dynamics of ecosystems, and searches for similarities across aquatic and terrestrial systems. The ultimate goal of his work is to develop a predictive ‘tool box’ to forecast how ecosystems will change in a world increasingly dominated by humans and the oceans.

Rod Wilson

Rod Wilson

Rod is a comparative physiologist. He aims to provide a more holistic understanding of homeostasis in aquatic animals, both fish and invertebrates, freshwater and marine. This includes studies of how anthropogenic and natural environmental changes impact upon physiology and behaviour in the wild, and how to use physiology to help improve the sustainability of aquaculture (including animal growth efficiency and health, pathogen/parasite resistance, and farm effluent output). He also studies the reverse process: how physiological processes in aquatic animals can influence the regional and global environment in freshwater and the oceans.
