I earned my PhD in 1984 at University of Aarhus, Denmark. Shortly after (1985) I was employed as Assistant Professor and from 1989 as Associate Professorat the Institute of Biology, Odense University (now known as University of Southern Denmark). I have through the years taught undergraduate and graduate courses in microbial ecology, biogeochemistry, marine biology and population biology. I have graduated more than 60 M.Sc. and 10 PhD’s. My research on sediment biogeochemistry and bioturbation in coastal areas have brought me to several interesting countries around the world, including Thailand, Australia, Tanzania, USA. My current research interests are primarily focused on the biogeochemistry and ecology of coastal marine sediments inhabited by burrowing invertebrates and rooted macrophytes. I am currently involved in the following projects: 1. The impact of burrowing infauna on organic matter and nutrient cycling in marine sediments. Species of the common polychaete genus Nereis are excellent model organisms for this purpose. 2. Colonization in recent years of the invasive polychaete Marenzelleria viridis in our coastal sediments has raised a number of new questions: 1. Wil this new species outcompete native species, such as Nereis diversicolor? 2. How does it affect the sediment biogeochemistry? 3. Partitioning of microbial respiration processes and release of greenhouse gases in bioturbated and rooted intertidal sediments. My objectives of this work is to determine the role of burrowing animals (various crab species and polychaetes) and roots (eelgrass, cordgrass and mangrove trees)for these processes.
