Curtis Picken

Environmental Scientist

Curtis is an environmental professional with a Bachelor’s degree in Ecology and Marine Biology and a Master’s in Marine Conservation. Curtis is particularly passionate about understanding the interactions between humans and the aquatic ecosystem, and how sustainable practices can be applied to protect and enhance the natural environment.

He joined Morphum in 2026 after gaining experience in both research and environmental consulting. His research focused on water quality, including the use of algal nutrient scrubbers and constructed wetlands to mitigate pollution from agricultural drainage and wastewater. As a consultant, Curtis has worked with iwi, councils, community groups, and infrastructure clients on the restoration and management of freshwater ecosystems. His experience includes fish passage assessment and design, wetland management, and baseline freshwater monitoring, encompassing fish, macroinvertebrate, and water quality surveys. He has also worked in the marine aquaculture sector, with a focus on detecting harmful algal blooms.

Outside of work, he enjoys spending time outdoors with family and friends, mountain biking, running, following rugby, and making the most of summer at the beach.
