Professor Steve Widdicombe leads the PML strategic science area Marine ecology and biodiversity. The research he oversees aims to develop novel approaches for measuring and describing biodiversity across a range of biological scales, investigate the relationships between biodiversity and the provision of key biogeochemical processes, and thus develop the understanding necessary to predict the impact of biodiversity change on the structure and function of marine ecosystems.

Steve is a marine ecologist with 25 years of experience in using field observations and manipulative experiments to address issues relating to benthic ecology, biodiversity and ecosystem function. He has a broad range of interests including bioturbation, microbial nutrient cycling, long-term patterns in benthic and pelagic communities and developing novel methods for observing and manipulating natural systems. He is particularly interested in quantifying the effects of disturbance on the structure, diversity and function of marine benthic organisms and communities. Much of his recent research has concentrated on the ecological impacts of increasing seawater CO2 levels, rising temperatures and expanding areas of hypoxia. Through this interest in CO2 research, Steve has developed an expertise in Ocean Acidification and in the potential biological impacts of leakage from CO2 Capture and Storage (CCS). 

He has published over 80 peer-reviewed papers and book chapters.
