Animal Locomotion

Cameron Tropea, geb. 1954, ist derzeit Leiter des Fachgebietes Strömungslehre und Aerodynamik im Fachbereich Maschinenbau an der Technischen Universität Darmstadt, wo er sich vor allem mit Forschung im Bereich der Fluidzerstäubung, der Aerodynamik und der Strömungsmesstechnik befasst. Seine Beschäftigung mit der Bionik umfasst die Aerodynamik des Vogelfluges sowie das Aufprallverhalten von Flüssigkeitstropfen auf strukturierten Oberflächen.
