Research Interests:

My research examines the interactions between macrobenthic organisms and environmental factors at various scales, typically combining field samplings and experimental trials with microscopic/cellular and biochemical analyses. The focus is on life-history strategies that have evolved in extreme and/or climate-change-sensitive environments (deep sea, cold waters). Breakthroughs in biology, ecology, evolution and conservation were made by my team over the past decade: (i) first evidence of lunar rhythms in the reproduction of deep-water taxa; (ii) first direct evidence of allogeneic fusion (chimerism) in a deuterostome; (iii) first demonstration of a functional relationship between fish larvae and deep-sea corals; (iv) first demonstration of active buoyancy adjustment leading to rapid dispersal in so-called sedentary benthic animals. Applied research segments include the impact of ocean acidification and various aspects of fisheries and aquaculture.
