“Using the power of protein engineering and evolution, we can convince enzymes to take what they do poorly and do it really well.”

American chemical engineer, Nobel laureate

Frances Hamilton Arnold is an American chemical engineer and Nobel laureate. She is the Linus Pauling Professor of Chemical Engineering, Bioengineering and Biochemistry at the California Institute of Technology. She won the 2018 Nobel Prize in Chemistry for pioneering the use of directed evolution to engineer enzymes. Her work has helped shape modern protein engineering, and her public remarks often reflect the practical and scientific value of experimentation, design, and discovery.
