Mustapha Bouallala | Cadi Ayyad University | Morocco

Prof. Mustapha Bouallala, from the Polydisciplinary Faculty at Cadi Ayyad University in Safi, Morocco, specializes in applied mathematics with a focus on variational and hemivariational inequalities, contact mechanics, thermo-viscoelasticity, and fractional‐order differential models. His work emphasizes the mathematical analysis, modeling, and numerical simulation of complex physical systems governed by non-smooth dynamics, memory effects, and time-fractional derivatives. He contributes to the development of analytical frameworks for contact problems involving viscoelastic materials, locking materials, and thermo-mechanical interactions. Through rigorous mathematical modeling and approximation techniques, his research advances the understanding of nonlinear evolutionary problems and supports applications in engineering mechanics, material behavior, and thermal–structural interaction systems.

Shinya Matsuzaki | College of Physics and Center for Theoretical Physics | China

Prof. Shinya Matsuzaki, based at the College of Physics and the Center for Theoretical Physics in China, is a theoretical physicist specializing in quantum chromodynamics (QCD), scale-invariant gravity, early-universe cosmology, and dynamical symmetry breaking. His research explores fundamental questions about mass generation, dark sector dynamics, electroweak phase transitions, baryogenesis, and axion-related phenomena. Through analytic modeling and high-energy theoretical frameworks, he investigates mechanisms such as top-quark condensation, dynamical scalegenesis, CP violation in QCD, and inflation driven by composite fields. His contributions provide new insights into the interplay between particle physics and cosmology, helping to advance theoretical understanding of the early universe and the origin of fundamental mass scales.
