Dr Marie Magnusson described how seaweed has the potential to revolutionise global food production. I am a phycologist (I study algae!) and lead a multidisciplinary research group delivering fundamental and applied science to underpin the development of a sustainable seaweed aquaculture industry in NZ. My leadership role has a strong focus on industry engagement, research supervision, commercial outcomes, and communication and outreach. My broad expertise covers algal production from early life-history stages and hatchery to grow-out, and algal biotechnology and bioproducts development. I am passionate about providing real-world solutions to people, communities, and industry using science, and about mentoring students to empower them to find their own path in applying their skills and passions. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
