Walker's research centered on bio-inorganic chemistry, especially heme protein chemistry. Walker examined proteins in bloodsucking insects[3] and cytochromes that transfer energy between cells.[4] Walker's early work was on porphyrins and their complexation with iron. She was able to obtain structural information about metal binding proteins.[5][6] A portion of her work relied on nuclear magnetic resonance, especially paramagnetic nuclear magnetic resonance spectroscopy, which she used to examine model heme and systems with proteins coupled to heme.[7]
Walker was elected a fellow of the American Association for the Advancement of Science in 1984.[8] In 2000 she received the Garvan–Olin Medal for scientific accomplishments by a woman chemist from the American Chemical Society.[9][4] In 2006 she received the Alfred Bader Award in Bioinorganic Chemistry,[10] and in 2011 she was elected a fellow of the American Chemical Society.[1] The Society of Porphyrins and Phthalocyanines awarded her the Eraldo Antonini Award for lifetime achievement award in 2020.[11]
