I am a professor in the School of Ocean Sciences and specialise in the field of marine benthic ecology. For my PhD I studied the adaptive value of migrations and nursery use for the intertidal bivalve Macoma balthica at the Department of Marine Biology at Groningen University, and I received the Annual VLIZ North Sea Award 2002 from the Flanders Marine Institute (VLIZ) for my PhD thesis. After completing my PhD in 2002, I started a postdoc at Bangor University, where I studied the impact of bottom trawling on the functioning of benthic invertebrate communities. I joined the lecturing staff in SOS in 2006 and was promoted to Reader in 2013. I was awarded a Personal Chair in 2017.

Research Interests

Jan Geert Hiddink is a marine ecologist with extensive expertise in measuring and modelling the response of benthic communities to disturbance and modelling recovery trajectories for these organisms. His research is focussed on gaining a quantitative understanding of the effect of disturbance (such as exploitation and climate change) on the biodiversity and functioning of marine benthic communities, and on how such effects can be mitigated. This research includes the effects of MPAs on the communities of benthic invertebrates and fish. Most recently JGH has been studying the effect of climate change on the biodiversity of marine organisms using time series. JGH aims to increase understanding of ecosystem functioning and distribution patterns by comparing empirical data with predictions of ecological models.
JGH has published 46 peer reviewed papers since 2001. His grant capture since 2006 totals over £3.5M.
