Notably, she pioneered the development of winter-grade palm biodiesel, addressing its limitations in temperate climates.
Her innovations, including the commercialisation of low pour point palm biodiesel, normal grade palm biodiesel plants and carotene-enriched Red Palm Oil, have transformed the industry. Dr. Choo's patented processes retain valuable phytonutrients, contributing to the sustainable growth of Malaysia's oil palm industry.
In alignment with the Economic Transformation Programme (ETP), Dr. Choo assumed stewardship of seven of the eight-point projects (EPPs) for oil palm under the ETP. Her vision extends beyond innovation, encompassing sustainability and climate change. She played a pivotal role in formulating the Malaysian Sustainable Palm Oil (MSPO) Standard, emphasising reduced greenhouse gas emissions and life cycle assessments.
Beyond her role at MPOB, Dr. Choo actively engages with the Malaysian Invention and Design Society (MINDS), fostering curiosity and creativity. Her dedication to sustainability, climate change and innovation has earned her international recognition, including an Honourary Doctorate of Science from the University of South Wales.
