I work with multi-species models using the "Gadget" model as a tool. I work on interactions between species, uncertainty, and the interface between the real world and models, as well as stock assessment.
Scientific interests include numerical modelling, age-length structured fisheries models, simulations of population dynamics, model uncertainties, the influence of natural and anthropogenic changes to the system, and the interaction between models and real-world data
Research concentrates on using age-length structured models to produce detailed, biologically realistic, single- and multi-species fisheries models. Such models can be used to investigate the dynamics of the fish populations, and gives the ability to produce a virtual “population” on which a variety of experiments can be conducted which would be impossible in the real world. Typical experiments include different harvesting strategies, climatic forcing, or the impacts of pollution such as oil spills. Such models also provide a complimentary assessment method to age-based modeling, and a method of producing stock assessments where age-based methods are unsuitable.
Has been employed as a researcher at IMR Bergen since 2002, and previously as a fisheries researcher at MRI Iceland. Has a PhD in glaciology, modelling the dynamics of the last ice sheet in Europe, and has also worked in the UK developing models to correct the UK Census for underenumeration (people who weren't counted in the census).
