Researcher biography

Biography

From a young age Marjoleine has been fascinated with all sorts of animals. During a trip around Australia in 2003 she had her first encounters with cetaceans at sea, she was hooked! 

In 2008 she completed the Bachelor of Science Wildlife Management (Van Hall Larenstein, University for Applied Sciences, The Netherlands). For an internship she studied the Indo-Pacific humpback and the Snubfin dolphin in Australia with the Southern Cross University Whale Research Centre (Lismore, Australia). For her thesis she studied the diet of cormorants, harbour porpoises and grey seals at Wageningen IMARES (The Netherlands).

She volunteered with the Center for Whale Research (Friday Harbor, U.S.A.) studying killer whales. Moved by her curiosity for dolphin therapy she also volunteered for the Dolphin Therapy and Research Center and the Sea Aquarium at Curaçao (Dutch Caribbean). Consecutively, she worked 1,5 years at the Conservation Research Center Marineland (Antibes, France) initiating and guiding several research projects; design and testing of a new non-invasive dolphin tag, pregnancy and birth in bottlenose dolphins and killer whales, respiration and behaviour in killer whales. Next to these activities she assisted in veterinary interventions in the park including sharks, polar bears, pinnipeds, cetaceans, turtles and birds.

In 2015 she completed her Master of Philosophy in Marine Mammal Science at the Sea Mammal Research Unit (SMRU) within the University of St Andrews, focusing on underwater activities and respiration timing in killer whales. Meanwhile, she was working as a research assistant with the University of St Andrews and the Sea Mammal Research Unit.

Marjoleine her main research interests focus on diving physiology, energetics, behaviour, breathing, and disturbance in cetaceans. She started her PhD with CEAL in January 2018 for which she is investigating the natural fine-scale behaviour and related energetics of humpback whales migrating away from their breeding grounds in Australia. An important aspect is the complex social structures among the groups and how this influences behaviour. It is expected that individuals experience different 'energetic pressures' dependent on their social contexts which are essential to investigate as a potential future tool to explore energetic consequences of changes in behaviour to anthropogenic noise
