Originally from Antwerp, Belgium, I have been involved in marine mammal research since 2002. My main interest relates to the field of conservation biology and associated management. With the use of science, I aim to understand the causal factors affecting marine mammal conservation in order to establish or improve conservation management strategies. Over the years, my research expertise grew in the areas of population biology, ecology and ethology.

Most of my work has been focussed in the South Atlantic, both in Argentina and South Africa;

While residing in Patagonia Argentina between 2005 and 2012, my research focussed on the abundance and behaviour of southern right whales and population ecology of bottlenose dolphins. Although being primarily a scientist, I strongly believe in a multidisciplinary approach to face the challenges within marine conservation. Therefore I founded and directed a local NGO, engaged strongly in public outreach (e.g. the children´s book “Toninas de la Bahia”) and aided provincial government with the establishments of provincial laws, regulations and educative programmes around the local whale and dolphin-watching and swim-with-whales programmes. Since 2009, I additionally worked as a marine consultant for the marine offshore industry, with expertise in European waters as well as the Mediterranean and South Atlantic.

Due to my broad interest in both science and policy, I joined the Belgian Delegation of the International Whaling Commission in 2011. Furthermore, I became more and more aware of the lack of connections and networking among the different stakeholders within nature conservation. This awareness gave rise to the idea to co-found Whalefish (www.whalefish.org), and NGO with which I aim to enhance educational outreach and improve networking possibilities. Indeed, I strongly believe that in order to achieve our conservation goal, it is not only important “what” we know, but also “who” we know!

Since 2014, I reside in South Africa where I attained permanent residency. Currently I work as the Research Manager and post-doctoral research fellow of the Mammal Research Institute Whale Unit of the University of Pretoria, and as PI of the Cape Town based NGO Sea Search (www.seasearch.co.za). Since my move to South Africa, I have successfully established a national humpback dolphin consortium (SouSA Consortium; www.sousaproject.org), facilitating a national collaboration among researchers to improve scientific data and therefore accurately advise conservation management. Additionally, I am focused on the  ecology, population dynamics and conservation of the South African population of southern right whales, building on a nearly 40 year-long database.
