I have carried out marine mammal survey and consultancy work for many organisations including Whale and Dolphin Conservation (WDC), Australian Antarctic Division (AAD), the North Sea Foundation (NL), PRO-SEA (NL), The Royal Netherlands Institute for Sea Research (NIOZ), Green Heritage Fund of Suriname, Sea Mammal Research Unit (SCANS2 Project), Marine Observers (Denmark), National Environmental Research Institute of Denmark (NERI), various Universities, e.g. Leiden (NL), Utrecht (NL), Exeter (UK), Plymouth (UK), Halifax (CA) and Wageningen (NL).

For a full CV or if you have any questions, please contact me via e-mail as I may be away at sea and well beyond the range of mobile phones.

Qualified Marine Mammal Observer (JNCC/PSO/MMS/GoM/IBAMA-Brazil)

Since 2006, I have worked as a qualified Marine Mammal Observer onboard geophysical survey vessels during expeditions offshore Angola, Gabon, Congo, Ghana, Ivory Coast, Namibia, Greenland, Labrador, Newfoundland, Faroese Islands, Shetland Islands, Central North Sea, Aruba, Curacao, Trinidad, Guyana, French Guiana and Suriname. During these surveys I also acted as a Protected Species Observer (PSO), Marine Mammal & Turtle Observer (MMTO) and Marine Mammal & Seabird Observer (MMSO) and assisted with Passive Acoustic Monitoring (PAM) on many occasions. I have also carried out marine megafauna surveys along Cape Verde, Mauritania, Senegal, Western Sahara, Morocco, Canaries, Azores, Madeira, Desertas, Celtic Sea, Bay of Biscay, Irish Sea and the English Channel.

Ph.D Study

I was educated at the University of Utrecht (Biology) and The Royal Netherlands Institute for Sea Research (MSc Marine Ecology, 1996), where I studied toxic algae blooms in the North Sea. I completed my PhD in 2013 at the University of Wageningen (NL) which focussed on Marine Mammal Ecology, studying the abundance and distribution of cetaceans using different methodology approaches and (low-cost) seagoing ‘Platforms of Opportunity’.

Wider Caribbean Region

My most recent research project is focusing on the marine fauna within the Guianas (Suriname and neighbouring countries) and I recently completed a project where I acted as a marine fauna scientist for an EU-funded project ‘Marine Spatial Planning’ in Suriname. I am also an experienced advisor to the MaMa CoCo Sea group (Marine Mammal Conservation Corridor for Northern South America) an initiative from the French Agency for Marine Protected Areas supported by the CAR-SPAW office for the Wider Caribbean Region. Several scientific papers and a book entitled ‘The Sea of Suriname’ on Marine Fauna, have been published in relation to my research in the waters offshore Suriname.


Since 2004, I have studied the cetaceans occurring off SW England during both offshore and inshore coastal surveys. I have published several papers regarding this work.  In 2007 I joined forces with ‘Marine Discovery’ of Penzance to oversee the data collection, photo-ID catalogues and analysis from this valuable research.

Wageningen Marine Research

I currently work as a guest employee for Wageningen Marine Research (Wageningen University in the Netherlands).


I have produced a wide selection of scientific publications and presented papers to various international conferences and committees. She also regularly peer-reviews scientific papers for a range of scientific journals.
