Reinhard Miller studied Mathematics at University of Rostock (1969-1973) and Colloid Chemistry at the Technical University Dresden (1977-1978), Germany. He got his PhD in 1978 and Habilitation in 1988, both at the Academy of Sciences in Berlin, Germany, on problems of adsorption kinetics and dilational visco-elasticity of surfactants. 1992-2015 Dr. Miller worked as Group-Leader at the Max Planck Institute for Colloids and Interfaces in Potsdam/Golm in the field of thermodynamics, kinetics and mechanics of surfactant and protein adsorption layers at liquid-fluid interfaces. 2015-2019 he was Senior scientist at the same Max Planck Institute for Colloids and Interface. Since 2020 he is Associate senior scientist in the Institute for Soft Matter Physics, TU Darmstadt. He is presently the Editor of the book series with Taylor and Francis "Progress in Colloid and Interface Science", (so far 7 Volumes). Dr. Reinhard Miller was President of the "European Colloid and Interface Society" ECIS (2012-2014) and President of the "International Association of Colloid and Interface Scientists" IACIS (2015-2018). His scientific interests are dynamics and mechanics of liquid interfaces, thermodynamics of adsorption of surfactants, proteins, polymers, particles and their mixtures, interfacial interactions and 2D shear and dilational rheology, formation and stability of foams and emulsions. He published about 715 papers in referenced journals (Web of Science), about 50 chapters in books, about 50 contributions to printed conference proceedings. He has a h-index of 67 (Web of Science), 70 (Scopus) and 84 (Google Scholar). ORCID: 0000-0001-8943-7521. Eduardo Guzmán was born in 1981 in Madrid (Spain) and is Associate Professor of Physical Chemistry at the University Complutense of Madrid (UCM), Spain. He received his Ph.D. in Chemistry at the University Complutense of Madrid in 2009 under the supervision of Prof. Ramón González Rubio and Francisco Ortega, where he carried out studies on the fabrication and physicochemical properties of polyelectrolyte multilayers obtained by the Layer-by-Layer method. From 2010 to 2014 he worked as a postdoctoral researcher with Dr. Libero Liggieri and Dr. Francesca Ravera (Istituto per l'Energetica e le Interfasi, Italy) on the effect of nanoparticles in the interfacial properties of models mimicking the behavior of the lung surfactant layer. In 2014, he returned to the UCM as Juan de la Cierva Fellow, obtaining an Assistant Professor position in February 2016 and then in March 2020 he was appointed as Associate Professor. He has co-supervised three PhD Thesis. He has been involved several EU and Spanish funded I+D grants and has been scientific responsible of 5 cooperation projects between academia and industry. He is member of the editorial board of different scientific journals, including Coatings (Editor in Chief of the Section "Liquid-Fluid Interfaces"), Polymers, Advances in Colloid and Interface Science and Colloids and Interfaces, and from 2023 he is coeditor of the book series Progress in Colloid and Interface Science
