Dr. Retamal Marín studied Mechanical Engineering at the University of Talca (Chile), where he obtained his degree in 2011. In 2021, he obtained a Ph.D. degree on the field of particle technology at the Technische Universität Dresden (Germany). Dr. Retamal Marín’s research focused on dispersing and stabilizing of nanoparticle suspensions, the characterization of multi-component materials containing nanostructured materials in complex matrices, the electrokinetic characterization of colloidal systems and the development as well as the implementation of particle measurement techniques for process analysis.
