Being born and raised in Venlo (The Netherlands) nearly 200 km from sea (which is pretty far away for Dutch standards), it is probably not very obvious how I became so fascinated by the marine environment and especially sharks. The answer however, is very simple: books and documentary films did the trick and inspired me at a relatively young age to determine and follow an unlikely path for the rest of my life. Every kid has his/her own favorite animal, I started of with snakes but soon switched to sharks and other marine megafauna with which I stayed for a while. Volunteering for a well-known marine conservation NGO for a couple of years also inspired me to found and direct my own ocean awareness and research project called Oceaware. After finishing my bachelor of Applied Biology (University of Applied Sciences HAS Den Bosch), I am now in my second year of my MSc. Marine Biology at Wageningen University.
Now, at age 25, I can proudly say that I was involved in many fascinating (research) projects, met and worked alongside many inspiring and dedicated fellow students and scientists from all over the world, and travelled to the most beautiful countries and islands. But above all, I worked with the most amazing wildlife in the Ocean. Fortunately, that’s not it, new exciting projects are up ahead in the near future of which I will keep you all posted through new blog posts.
If you have any inquiries, tips or just want to get in touch, do not hesitate to contact me.
