Ralf Bachmayer

Prof. Dr. Ralf Bachmayer hat zum 1. Juli 2017 die neu eingerichtete Werner Siemens-Stiftungsprofessur „Marine Umwelttechnologie / Tiefsee Ingenieurwissenschaften“ im Innovationszentrum für Tiefsee-Umweltüberwachungen am MARUM, Universität Bremen angetreten. Sein Forschungsschwerpunkt liegt im Bereich des Entwurfs und der Steuerung vernetzter heterogener Unterwasserbeobachtungssysteme zum Zwecke effizienter Langzeit Tiefseebeobachtungen. Er ist Leiter der Arbeitsgruppe Marine Umwelttechnologie / Tiefsee Ingenieurwissenschaften am MARUM.

Prof. Bachmayer hat Elektrotechnik in Karlsruhe studiert, die Diplomarbeit hat er am Woods Hole Oceanographic Institution (USA) verfasst und an der Johns Hopkins University (USA) promoviert. Seit seiner Post-Doktoranden Stelle an der Princeton Universität (2000-2003) arbeitet er mit und an verschiedenen Technischen Aspekten von Unterwasser Gleitern (Modellierung, Regelung, Navigation) individuell aber auch als mobile koordinierte oder kooperierende Netzwerke verknüpft. Von 2003 bis 2008 war er wissenschaftlicher Angestellter am National Research Council Canada Institute for Ocean Technology in St. John’s, Neufundland. 2008 wechselte er an die Memorial University of Newfoundland wo er das Autonomous Ocean Systems Laboratory (www.aosl.ca) gründete. Seit 2017 baut Prof. Dr. Ralf Bachmayer am MARUM das durch die Werner Siemens-Stiftung geförderte Innovationszentrum für Tiefsee-Umweltüberwachung auf.
