Her research group on Macromolecular Crystallography (http://sites.fct.unl.pt/xtal) has several areas of interest focused on molybdoenzymes (aldehyde oxidases, arsenite oxidases and formate dehydrogenases) and their enzymatic mechanisms, glycan-binding and cellulosomal proteins and methods for protein crystallization. She has supervised/co-supervised 15 PhD students and is the Principal investigator in 7 project(s) and Researcher in 24 project(s). In the period 2012-2022 she was the Portuguese Delegate to the European Synchrotron Radiation Laboratory (ESRF), is the Portuguese observer at the Scientific Advisory Committee of ALBA Synchrotron and, since 2017, Co-Editor of Acta Crystallographica F.
