Hey, I’m Marijke. I’m a published pop-science content writer who loves fishkeeping, marine biology, ornithology, houseplants & gardening, food, and travel.
Looking for accessible but scientifically sound contributions to your print magazine or online publication? Just published a fascinating study and want someone to tell the world about it? Or maybe you run a blog or eCommerce shop? Podcast? YouTube channel? Something else entirely? If you’re in need of content about the natural world (or how to bring it into one’s home), I’m here to help.
From deep scientific features into ocean symbioses to reptile care guides, aquarium product reviews to scientific and conservation communications: great content makes all the difference, and I can write it for you. I love nothing more than telling readers about the wonders of the natural world, how to protect our planet, and helping them with their nature-related hobbies.
Need science comms but don’t know where to start? Tired of low-quality, unoptimized blog content? Overwhelmed with having to write your podcast scripts yourself? Got a web page in need of updates?
Why work with me?
Niche website owner
I’ve been building and selling niche websites since 2013, so I know all the joys and pitfalls of running a business. In fact, owning my own sites is what brought me to freelance writing in the first place!
10 years of experience
After landing my first client, I never looked back. I’ve since written over 1000 articles for over a dozen happy clients. Some of them have been with me for years and always come back for more!
Broad interests
My main niches are related to pets (especially aquariums and parrots), nature, and food. However, I’m always willing to dive into new topics and expand my knowledge to bring you the best content for a range of niches.
Love my job
My philosophy is that if you love what you do, the rest will follow. Few things make me happier than diving into—and “translating”—obscure scientific studies about our world’s fascinating flora and fauna.
What can I help you with?
From simple blog content optimization to well-researched, scientifically slanted magazine articles, I’m here to help.
- Investigative deep dives
- Pop-science articles with sources
- SEO-optimized website content
- Blog post optimization
- Content SEO audits
- Proofreading & editing
- Underwater, nature & product photography
- Writing & translation in English, Dutch & Spanish
Because I’ve got access to keyword finding tools and scientific articles, you can count on the soundness and relevancy of all content.
Testimonials

I have been working with Mari for the last 4+ years. She is the best freelance writer I have ever worked with. I turn to her for all my content needs no matter the topic!
She is excellent at research and gets the job done flawlessly everytime!
– Ryan Curtis from The Shrimp Farm & House of Arcade, Bloomington

I went through several writers before finding Mari and was so frustrated with the poor quality of work. Mari is heads above any writer I or my fellow blogging friends have experienced. Her research on any topic you throw at her is in-depth, she picks up on your voice and requirements quickly, she is a whiz at SEO, she is timely-reliable-honest, and the cherry on the cake is that she is fun! Can’t recommend enough.
– Dorothy from Farm to Jar
