CV SUMMARY FOR:

I am in a researcher at the Centre for Ecological and Evolutionary Synthesis (CEES) a centre of excellence in the department of biosciences of the University of Oslo in Norway. My main working topic is to analyze the trophic interactions in regard to the environmental variability. I am looking particularly into the relationship between food abundance, time synchrony and reproductive success (to have more detail on my work see also my page at the CEES). I am fully involved in the marine research conducted at the CEES by running the monthly meetings. I wrote my PhD while in France at the Centre d’Écologie et Physiologie Energétiques (new name DEPE) in ecophysiology focusing on the energetic constraints put on the organisms by the environment during their annual cycle (reproduction, growth, wintering). During the same period and for seven years I was statutory teacher of biology and geology at different school levels.

My research effort is mainly aimed at understanding the impacts of environmental variability on the population dynamics and phenology with special focus on marine populations and in an earlier life on seabirds. In other words I try to understand how population answer to these changes. I am particularly looking into the relationship between food abundance, time synchrony and reproductive success/recruitment. For this I am using historical time series analysis techniques. I used a significant part of my time studying ecosystem functioning using the match-mismatch hypothesis of David Cushing as a framework. I did this mainly on the Lofoten - Barents Seas system but also on the Southern Ocean and the Benguela Upwelling to give only two other systems.

I also address the question of the vulnerability of marine systems to environmental changes, using seabirds, which are among these ecosystems' main top consumers, as indicators.

I also study how climatic changes, expressed by different factors (weather package such as North Atlantic Oscillation, or Sea temperature…), influence different parameters of the food chain to which the seabird (e.g., Atlantic puffin Fratercula arctica, king penguin Aptenodytes patagonica) is the top predator. In this context, I studied three trophic levels: the plankton, the forage fish available for the seabird (e.g. Herring Clupea harengus for the puffin) and the seabird. Recently I broadened my scope with studies on other food chains such as fish-pelagic fish-plankton.
