We are currently looking for a new postdoc. See our Team page. Harnessing the Power of Plants to Combat Climate Change Plants are quiet but amazing. Every year, plants absorb an astonishing amount of carbon dioxide (CO2) from the air. This process, known as plant metabolism, allows them to harness the power of sunlight and convert CO2 into a wide range of essential chemicals. The impact of plant metabolism goes beyond just cleaning our air. The chemicals produced by plants serve as vital ingredients in our everyday lives. They contribute to our food, animal feed, energy sources, fabrics, medicines, and countless other materials we depend on. The Maeda lab fosters collaboration among diverse students and scientists to unravel the intricate workings of plant metabolism. By understanding these complex processes in various plants, we strive to discover innovative solutions to combat climate change. Harnessing the remarkable abilities of plant metabolism will pave the way for a greener, more sustainable future. See also Maeda's WSJ story. Read more about our research projects here. Maeda Lab welcomes people having diverse backgrounds and experiences at different career stages. Our culture of respecting and bringing together each person's strengths and ideas facilitates creative and robust approaches to answer innovative questions. Diversity is our driving force to scientific exploration and professional, social, and personal growth. Read more about our commitment and efforts here. Lab News NEW 2024 Nov.
