• RESEARCH
My research is focused on granular materials from a modeling perspective and in a cross-disciplinary context involving physics and mechanics, with applications to geomaterials, powder processing, geological surface processes, and some biomaterials. My papers on micromechanical analysis of stress transmission (strong and weak subnetworks), stress partition (force and fabric anisotropy) and scale-dependent nonaffine velocity fields (granulence) are among the most cited papers in the field. My two papers on force transmission in granular media in 1996 and 1998 have been cited nearly 1000 times. I had the highest number of citations in Phys. Rev. E in the field during 2007-2017 over 1000 papers [see article by W.-F. Oquendo and N. Estrada, “Some statistics about research on granular materials during the last decade”, EPJ Web of Conferences 140, 16006, 2017]. I popularized the contact dynamics method for discrete simulation of granular materials, and developed advanced particle dynamics algorithms for complex granular materials. During the last 10 years, I carried out the first extensive parametric simulations of submerged granular flows, packings of polyhedral, elongated and nonconvex particles, and strongly polydisperse granular materials. I also analyzed the influence of such realistic material parameters on the rheological behavior (shear strength, dilatancy, anisotropy, connectivity). I was visiting scientist in MIT for three years, and invited by several prominent scientists to give seminars in Boston, Chicago, Durham, and New York City. I have 113 papers in peer- reviewed journals (including 3 review papers, 1 Sci. Rep., 7 Phys. Rev. Lett.), 6 books, 31 book chapters, 70 publications in proceedings, 237 communications in national and international workshops, 61 invited talks in national and international workshops, 37 invited seminars in universities in France, USA, Colombia, and UK, 15 populariation articles, 2 patents, and 5 softwares (referenced by Renater).
