53:09Now PlayingMarine ecologist, Pia Winberg learned how useful seaweed could be for gut health and wound healing. One day she was conducting research by herself in her lab when she had a terrible accident.
Pia was four-years-old when she moved from her native Sweden to Australia.
She always loved the beach and the coastline.
As an adult, Pia became fascinated with the scientific properties of seaweed after visiting a Sri Lankan prawn farm using seaweed to bolster the health of the surrounding environment.
She became a marine ecologist in Wollongong south of Sydney, looking at the unique ways seaweed could help clean the ocean and help people with various ailments.
In 2015 Pia set up her own seaweed farm, on the edge of an alcohol distillery in the town of Nowra.
One day she was emptying seaweed extract from a tank when a large section of her scalp was torn away from her head by a machine.
The accident could've killed her if she'd fainted. Instead Pia walked 200 metres from the factory to her office, to tell her staff what had happened.
Further information
2025 update: Pia has now had six reconstruction surgeries, and seaweed gels have played a huge part in her healing. Pia explains: using Phyaluronic formulations, which we coined to describe seaweed gels that mimic human tissue, has been transformative in my recovery… I am now 90% reconstructed on top.
Originally broadcast July 2019.
