Research profile

My research has mainly contributed to filter feeding, bioenergetics and fluid mechanical analysis of filter-pumps in marine invertebrates. Key words: filter-feeding in marine invertebrates; bioenergetics (food-uptake, assimilation, respiration, energy budgets, growth, costs of growth, growth efficiency); biological filter-pumps; biomixing; fluid mechanics; population grazing impact; particle capture mechanisms; benthic-pelagic coupling; biological structure and nutrient dynamics; grazing impact of benthic filter feeders; implications of density driven currents for interaction between jellyfish and zooplankton. Several research sojourns, among them: Skidaway (USA), Woods Hole (USA), University of Wales (U.K.), Kristineberg Marine Research Station (Sweden).

Membership

Member of the Danish Academy of Sciences (DNA). Member of the steering commitee for the Biodiversity Research Programme, the Research Council of Norway (Sept 2004 – Dec 2007). Member of the Nordic Marine Academy (NMA, key supervisor Jan 2005). Member of the board of Danish Center for Marine Research (until March 2012).

Miscellaneous

In 1990, I established the small Fjord Biological Laboratory in Kerteminde which in 1997 became a part of the new Marine Biological Research Centre in Kerteminde. I have supervised some 50 candidate (M.Sc.) research-projects, and supervised or co-supervised 10 Ph.D. projects; organized a number of international Ph.D. courses. I have received substantial support from the Danish National Research Council, private funds, and from a number of major grants from national research agencies, and EU research programmes.
