More information about Robert Verpoorte


Over the years the natural products laboratory  has studied various aspects of  natural products. This included the isolation and identification biological active compounds, their biosynthesis and metabolic engineering of relevant biosynthetic pathways. In recent years the development of metabolomics and the natural deep eutectic solvents have been the major interests. The work resulted in more than 800 publications, 6 patents and 3 books. The research is widely cited and places him is among the 1% most cited authors in Clarivate, Web of Science (Cross-Field)(2018, 2019, 2020 and 2021). A citation analysis made by Stanford University placed the impact of his work on position 45 (out of 134,814 authors) in the field of chemistry (2020, 2021).
