She was appointed a professor of computational materials science at University College London in 2007. De Leeuw designed computational models of olivine dust grains, a mineral that is common to the solar system, and studied how it interacted with water at high temperatures.[8] She demonstrated that the grains could hold water at temperatures up to 630 °C.[9] She studied the chemistry of hot vents on the sea floor, which De Leeuw proposed could produce the organic molecules essential for life.[10] She has also investigated biomaterials, such as the carbonated hydroxyapatite present in bone and teeth.[11][12][13][14] She investigated the nucleation of calcium carbonate.[15] De Leeuw was awarded a Royal Society Wolfson Research Merit Award in 2010.[16]
On 31 May 2019, it was announced that de Leeuw would take up the newly created post of executive dean in the newly formed Faculty of Engineering and Physical Sciences at the University of Leeds on 1 January 2020.[28]
