Lidia Tajber

My areas of research include the fundamental investigations into pharmaceutical crystalline and non-crystalline materials including multicomponent systems such as salts, cocrystals and ionic liquids for the advancement of pharmaceutical formulations. The emphasis of the research work is to improve physicochemical properties of the active pharmaceutical ingredients, especially solubility and processability, to improve bioavailability of drug substances. Specific areas include solid state transformations and reactions, anti-crystal engineering (ionic liquid and deep eutectic forms) and well as amorphous salts and the amorphous polymeric salt formation. My research activities fit with the national (Irish) policy objectives supporting the development and production of a highly educated and relevant workforce in demand by the pharmaceutical industry. Expertise includes the application of thermal analysis and spectroscopy for the monitoring of solid-state transitions and proton transfer reactions, pharmaceutical processing, such as spray drying, milling and hot melt extrusion and (bio)pharmaceutical testing such solubility, dissolution and permeability assessments.
