Lorena has a degree in biochemistry (FFyB – UBA). She obtained a PhD in Chemistry (FCEyN – INQUIMAE – UBA) working on the functionalization of different surfaces with composite materials to develop electrochemical sensors. She carried out postdoctoral studies at the Soft Matter Laboratory of the Instituto de Investigaciones Fisicoquímicas Teóricas y Aplicadas (INIFTA) on charge transport in supramolecular films formed by polyelectrolyte-surfactant complexes. She also carried out teaching activities at the Universidad de Buenos Aires (FCEyN – INQUIMAE).

Currently, Lorena is a CONICET staff researcher at the Soft Matter Laboratory. Her research projects involve the design of functional macromolecular nanoarchitectures, in two main areas: the design, synthesis, and physicochemical characterization of nanoparticles and surfaces with different functional properties, applied to the controlled release of bioactive molecules, and the development of supramolecular materials and surface modification techniques for the manufacture and optimization of biosensors.
