Dr. Humberto Jair Híjar Juárez is a Physicist who earned his Ph.D. in Physics with Honors from the Institute of Physics at the Universidad Nacional Autónoma de México (UNAM), where he was awarded the Alfonso Caso Medal for University Merit. He completed a postdoctoral fellowship supported by the German Academic Exchange Service (DAAD). He has built an extensive academic career in research and university teaching across public and private institutions in Mexico. He has been a member of Mexico's National System of Researchers (SNII) since 2009. He currently joins the Complex Systems Group at the Universidad Autónoma Metropolitana Unidad Iztapalapa as a Visiting Professor.

His scientific work specializes in non-equilibrium statistical mechanics, computational physics, and mesoscopic simulation methods, focusing on developing numerical algorithms and computational methodologies to bridge microscopic dynamics, mesoscopic transport, and emergent collective phenomena in complex systems. His research framework combines statistical mechanics, molecular dynamics, particle-based simulation methods, and continuum theories.

Key research contributions include the development and extension of Multi-Particle Collision Dynamics (MPCD) to nematic liquid crystals and hybrid computational models to investigate thermal fluctuations, hydrodynamic interactions, orientational order, topological defects, and non-equilibrium transport. His study topics encompass confined soft matter, nematic liquid crystals, active matter, and colloidal systems, supported by extensive expertise in scientific and high-performance computing alongside national and international research collaborations.
