Peter Ralph

Distinguished Professor Peter Ralph is a leading expert in algae biotechnology, specialising in the development of sustainable algae‑based solutions for food, energy and high‑value bioproducts. As Executive Director of the Climate Change Cluster (C3) at the University of Technology Sydney, he leads internationally recognised research focused on mass‑scale algae cultivation and highly photosynthetically efficient systems that address key commercialisation barriers in the algae biotechnology sector.

His research spans bioplastics, advanced manufacturing and zero waste biorefinery approaches, contributing directly to the development of a circular bioeconomy and scalable climate solutions. A strong emphasis of his work is research translation, and he collaborates closely with dozens of domestic and international industry partners to accelerate the uptake of algae based technologies into real‑world applications.

Professor Ralph is the Founder of the NSW Deep Green Algae Biotech Hub, where he has supported entrepreneurs to establish new algae focused ventures. With more than 400 publications and over $18 million in research funding, his work plays a pivotal role in mitigating climate change through carbon capture and sustainable biotechnological innovation.
