About
Safya Belghith is a prominent researcher specializing in nonlinear dynamics, chaos theory, and bipedal robotics, with a particular focus on the passive and semi-passive dynamic walking of biped robot models. Her work centers on understanding and controlling the complex dynamical behaviors that emerge when biped robots traverse sloped surfaces, including bifurcations, chaos, and intermittency phenomena. Among her most significant contributions is the development of explicit analytical expressions for the Poincaré map — a powerful mathematical tool for analyzing periodic motion — applied to the compass-gait and torso-driven biped models. These formulations, detailed in papers accumulating over 60 citations each, have enabled more precise stability analysis and control design. Belghith has also pioneered the application of OGY-based chaos control strategies to semi-passive bipedal locomotion, revealing rich dynamical phenomena including Neimark–Sacker bifurcations, torus bifurcations, and boundary crises. Her research has collectively garnered hundreds of citations, reflecting its substantial influence on the robotics and nonlinear dynamics communities. By bridging rigorous mathematical analysis with practical control applications, Belghith's work has meaningfully advanced the understanding of how human-like walking robots can be stabilized even under inherently chaotic conditions.
