Wil J.M. Landman

‘Scientia ducet’ id est ‘science leads the way’. Nothing has brought more wealth and happiness to humanity than science; it has saved us from ignorance and suffering and continues to do so day by day. Walking the unknown, finding the answer to questions that have not been addressed by anyone before is what I love about my job. Most of it concerns applied research on the pathogenesis and prevention of a number of relevant poultry diseases. Occasionally, my research concerned other species as well, e.g. humans and swine, adding new dimensions to an already thrilling job at Royal GD.'  Wil Landman
