In the rapidly evolving world of food technology, few names resonate as profoundly with innovation and sustainable development as Professor Mark Tester. As a luminary in plant science at the King Abdullah University of Science and Technology (KAUST), Professor Tester has dedicated his career to addressing some of the most pressing challenges in agriculture. Serving as the Associate Director of the Center for Desert Agriculture, his work is pivotal in transforming arid landscapes into fertile grounds for food production. Professor Tester's journey in plant science is marked by significant achievements and contributions. Before his tenure at KAUST, which began in February 2013, he was celebrated as an ARC Federation Fellow and professor of plant physiology at the University of Adelaide. It was there he spearheaded The Plant Accelerator initiative, a cornerstone in plant phenomics research. His academic prowess was nurtured at the University of Cambridge, where he not only served as a Senior Lecturer but also earned his PhD in 1988, laying the groundwork for a career that would become synonymous with groundbreaking research in plant science. In 2019, Professor Tester took on the role of Head of the Food Sector at NEOM, demonstrating his versatility and commitment to advancing food security and sustainability on a global scale. However, it is perhaps his role as co-Founder and Chief Scientist of Iyris formerly known as Red Sea Farms that best encapsulates his vision for a sustainable agricultural future. At Iyris, Professor Tester is at the forefront of developing innovative saltwater-based agricultural systems. This revolutionary approach not only promises to significantly reduce freshwater use in agriculture but also offers a resilient solution to food production in some of the world's most water-scarce regions. Through his pioneering work, Professor Tester is not just redefining the boundaries of agricultural science; he is actively contributing to the global effort to ensure food security in the face of climate change and limited natural resources. His dedication to developing sustainable food production systems reflects a deep commitment to the planet and its inhabitants, making him a beacon of hope and innovation in the quest for a more sustainable and food-secure world. As we sit down with Professor Tester on the FoodTech Junkies podcast, we delve into the mind of a scientist who is not only shaping the future of agriculture but also inspiring a new generation to think differently about how we grow our food.
