Expertise and research interests

Prof. Johan Wouters is leading a research group focusing on structural biological chemistry. His lab develops research projects falling within the field of medicinal chemistry and is an active member of the Namur Medicine & Drug Innovation Center (NAMEDIC). The research activities rely on a strong expertise in X-ray crystallography. Crystallography is a major tool for structure-based drug design, as it allows knowledge of the 3D structure of protein targets. In this context, researchers of the lab produce, purify, characterize and crystallize enzymes of pharmaceutical interest. Furthermore, X-ray crystallography is also used to determine the structure of small molecules with therapeutic potential. Researchers are focused on the preparation and physicochemical characterization of pharmaceutical cocrystals. The main research areas are cancer and infectious diseases.
