As a marine ecologist with nearly 30 years of experience, Steve is an expert in using field observations and large manipulative experiments to address issues relating to benthic ecology, biodiversity and ecosystem function. In particular he is interested in quantifying the effects of natural and anthropogenic disturbance on the structure, diversity and function of marine benthic communities.

He has played key roles in several national and European funded projects exploring the impact of environmental impact and change on marine ecosystems and biogeochemical cycling. Steve started his research career looking at the impacts of natural disturbance (bioturbation) on marine biodiversity and community structure, and has continued this research theme ever since. In addition, much of his recent research has concentrated on the impacts of climate change on benthic organisms and ecosystems.

He has been a principal investigator in a number of large NERC programmes including Shelf Seas Biogeochemistry, Arctic Change and Marine Ecosystems, and led a large consortium within the NERC UK Ocean Acidification Programme.

Steve has an active interest in monitoring the marine environment and established the North East Atlantic regional hub of the Global Ocean Acidification Observing Network (GOA-ON). In 2014 he was awarded a visiting Professorship in Marine Ecology by the University of Plymouth, in recognition of his contribution to Climate Change research as well as MSc and PhD student supervision.
 
He has published 150+ peer reviewed papers and book chapters, and has an H-index of 43 (WoS).
