DR Rob Kinley

Discovered the Asparagopsis Methane Effect

Dr Rob Kinley is an internationally recognised agricultural scientist specialising in the environmental and nutritional aspects of livestock and food production. With a background spanning analytical chemistry, soil science, environmental science and animal biology, Rob has dedicated much of his career to developing practical solutions that improve livestock productivity while reducing agriculture’s environmental impact.

During his time as a Senior Research Scientist and project leader with CSIRO Agriculture and Food, Rob played a pioneering role in the research that identified the extraordinary methane-reducing potential of Asparagopsis seaweed in cattle and sheep. His work helped drive the development and commercialisation of the technology that ultimately became FutureFeed, where he went on to serve as Chief Scientist.

Rob has more than three decades of experience across agricultural research, environmental science and livestock systems in Australia and internationally. He has authored and contributed to numerous scientific studies relating to Asparagopsis and enteric methane reduction and is widely recognised as one of the leading scientific voices in the development of seaweed-based solutions for lower-emission livestock production.

Zoe HOpKINSON

Production Technician

In 2023 Zoe completed a Bachelors in Coastal and Marine Science at Curtin University. During her study Zoe also gained work experience as an aquaculture volunteer, including roles with PhD students and Department Primary Industry Resource Development (DPIRD).  In addition Zoe worked at the Geraldton TAFE commercial hatchery, which introduced her knowledge to cultivate Asparagopsis seaweed and aquaculture operations.
Within completing Zoe's degree, she also completed field work studies on fish behaviours and interacted with multiple marine based professionals.  Zoe had access to innovative technology that made her learning & experiences much more immersive and accessible, enabling her to gain experience in technologies, equipment and platforms used within the aquaculture research industry.  Zoe is thrilled to be a part of the Seastock science team, which has further ignited her passion for the ocean and participating in work which will benefit the state of our climate. Working towards a more positive future for all.
