Leonard Sagis

Leonard Sagis obtained an MSc in Chemical Engineering from Eindhoven University of Technology in 1990, and a PhD in Chemical Engineering from Texas A&M University in 1994. In 1998, after postdoc positions at the physical chemistry department of Leiden University and the Institute of Technical Chemistry of the University of Amsterdam, he joined Wageningen University, where he is currently a faculty member in the Physics and Physical Chemistry of Food Group. Since 2011 he is also a member of the Polymer Physics Group of the Department of Materials, at ETH Zurich in Switzerland. His research interests are in the field of Soft Interface Dominated Materials, such as emulsions, foams, microcapsules, or hydrogel beads, and in particular in the relation between the microstructure of these systems, and their properties and stability. His current focus is on the nonlinear dynamic behavior of oil-water and air-water interfaces stabilized by anisotropic colloidal particles or soft hydrogel nanoparticles (Pickering systems), and interfaces stabilized by amphiphilic biopolymers. He is also involved in the design of multipurpose nanoparticle-based delivery systems. He uses a multidisciplinary multiscale approach to study these systems, which combines experimental methods (bulk and surface rheology, scattering techniques, microscopy), computational methods (MC, NEMD simulations), and theoretical methods (nonequilibrium thermodynamics).

Críspulo Gallegos

Críspulo Gallegos (Sevilla, Spain, 1955) obtained his PhD at the Chemical Engineering Department of the University of Sevilla (1982, Sevilla, Spain).
Since May 2011, he is Vice-President & Head of I&D “Complex Formulations” of Fresenius Kabi Deutschland GmbH (Germany). He is also Full Professor of Chemical Engineering at the University of Huelva (Spain). Among other universities, he has worked as Visiting Professor (1989) at the University of Laval (Québec, Canada) and as BBVA Professor (1998) at the Chemical Engineering Department at Cambridge University (UK). Since 2006, he is an invited “Associated Member” of the Institute of Non-Newtonian Fluid Mechanics (UK).
His research is mainly focused on microstructured product engineering. He has published to date over 250 scientific papers on this subject. In addition, he has participated in more than 100 research projects sponsored by different public administrations or the industry. He is also co-inventor in more than 25 patents, and Director of 16 Ph.D. Thesis on Complex Fluids Engineering.
He is Topic Coordinator Editor on “Materials Processing and Product Development” of the journal “Chemical Engineering Research and Design” (Elsevier), and Associate Editor of “Mechanics of Time-Dependent Materials” (Springer).
Crispulo was the Scientific Coordinator of the Food Technology Area of the National Agency for Evaluation and Foresight of the Spanish Ministry for Science and Technology (2001-2004).
He was the President of both the Spanish Group of Rheology (1993-2006) and the European Society of Rheology (2009-2013).
Since 2011, he is a fellow of the European Academy of Sciences and, since 2012, fellow of the International Academy of Engineering (Russia).
