About

Hanieh Mohammadi is a leading researcher in the field of robotic control systems, with a primary focus on assistive and rehabilitative technologies. Her work centers on the intersection of optimal control, energy efficiency, and human-robot interaction, particularly for lower-limb prostheses. In her highly cited 2017 paper, "Optimal Mixed Tracking/Impedance Control With Application to Transfemoral Prostheses With Energy Regeneration," she pioneered a novel control framework that seamlessly integrates tracking and impedance control while incorporating energy regeneration. This breakthrough allows robotic joints—both actively and semi-actively controlled—to operate with significantly improved power efficiency, a critical advancement for battery-powered prosthetic devices. By designing an optimal passivity-based system, Mohammadi demonstrated how regenerative actuators can capture and reuse energy that would otherwise be dissipated, extending device usability and user mobility. Her work, which has garnered over 30 citations, represents a foundational step toward more sustainable, intelligent, and responsive prosthetic limbs. Mohammadi’s contributions are shaping the future of wearable robotics, offering transformative potential for individuals with limb loss.
