Elżbieta Łastawiecka received her M.Sc. degree in Chemistry from the Faculty of Chemistry, Maria Curie-Skłodowska University (UMCS), Lublin, Poland, in 2005. Her master's thesis, entitled "Synthesis of an Atropisomeric Monodentate Phosphine Ligand", was carried out under the supervision of Prof. Kazimierz Michał Pietrusiewicz. She completed her Ph.D. studies at UMCS in 2010, defending a doctoral dissertation entitled "Design and Synthesis of New P-Chiral Phosphorus Ligands for Asymmetric Catalysis". The dissertation received excellent reviews and was nominated for distinction. Since obtaining her Ph.D., she has been affiliated with the Department of Organic Chemistry at UMCS. She broadened her scientific expertise through research internships at F. Hoffmann–La Roche (Basel, Switzerland, 2009) and as a postdoctoral researcher in the group of Prof. Alexandre Alexakis at the University of Geneva (2013–2014), where she worked on asymmetric bromine–lithium exchange reactions and the synthesis of atropisomeric compounds. Her research combines organic synthesis, heterocyclic chemistry, organophosphorus chemistry, asymmetric catalysis, medicinal chemistry, and sustainable synthesis. In recent years, her work has expanded toward biologically active heterocycles, biomass valorization, levulinic acid transformations, and fluorescent sulfolene derivatives with anticancer potential.
