Key personnel

Cleo N. Stratmann MSc
Environmental Specialist

I am Cleo Stratmann, an environmental researcher and engineer with a passion for collaboration and systems thinking. My goal is to resolve plastic pollution and apply knowledge, data, research, and technology where it is relevant to build a healthy environment and a sustainable and nature-loving society.

Most of my free time is spend in nature surfing, running, playing volleyball, handcrafting, traveling, sometimes photographing, and even the ‘geeky’ hobby of bird observation has become one of my favorite actives.

I can’t imagine a world without plenty of healthy nature around. That’s what drives me. I’ve been born with a curious mind, openly talking to people, finding creative solutions (inside and outside the box), eager to explore and protect nature. Now, I do this professionally. You’re welcome to join me on this endeavor.

Professional background

With more than 8 years of professional experience in the fields of freshwater ecology, environmental plastic pollution, and interdisciplinary research, I continue my commitment to environmental conservation and resolving plastic pollution issues. My experiences at internationally renowned institutions involved interdisciplinary and cutting-edge research, providing me with the network and skills to deliver high-quality work. With a master’s degree in Environmental Science and Technology and many years of professional experience including a top doctoral research project at the Ecole des Ponts ParisTech in France on the subject of freshwater microplastic pollution, I have in-depth knowledge in the field of technical environmental protection.


– Masters degree in Environmental Science and Technology from Technische Universität Berlin

– Experiences in waste assessment services

– Freshwater studies at large mesocosm facilities on anthropogenic impacts and climate extremes

– Research and monitoring plastic pollution specifically freshwater microplastics (PhD project)

Together, we provide support for your marine and maritime environmental endeavors and larger research-to-industry projects.

Together, we provide extended science communication services linking behavioral science and plastic pollution.

Together with and for NTNU, I engaged in education on the topic of plastic pollution.

I work with Act! to raise awareness for plastic pollution and ocean protection.

I am a scientific committee member and support the development of global South-North research-industry innovative exchange and partnerships.

Slide 3

Dr. Julie Hopper, Sustainability data analyst, University of Southern California, USA​

“Cleo is an amazing teammate, always willing to go the extra mile to solve a problem and to get the job done (and a job well done at that!). Cleo and I worked together during the 2021 Scripps-Rady Ocean Plastic Pollution Challenge where she taught herself QGIS in a matter of weeks and created beautiful maps for our team to display plastic pollution hotspots in the San Diego Area. (…) If you want your team and projects to excel then I highly recommend hiring Cleo! ”
