Details of specialism

In general terms I am interested in the study of population connectivity and the effects on environmental variations on fish populations. I am using  a range of natural and artificial tags (otoliths, mark-recapture, life-history trait variations) to assess fish movements and inform management decisions (MPA, stock identification). I am also interested in identifying the drivers of fish recruitment, with a focus on early life-history of fish and the impact of environmental variation (e.g. climate change) on how larval fish meet their energetic requirements (e.g. trophic match/mismatch).

Within the broad topic area my particular focuses currently include:

• understanding the population structure of cod, sandeel, skate and deep-water fish in the North Sea and North East Atlantic
• understanding the role of climate change on the abundance of forage fish and the structure of marine food-webs
