Congratulations to Dr. Haochen Wei

Congratulations to Dr. Haochen Wei on the certification of her PhD thesis! The thesis, titled “A Study on Stair Gait Phase Detection and Stair-Aware Module for Lower-Limb Exoskeletons,” presents a framework that incorporates an LSTM-CRF-based gait phase detection model and a vision GNN–based environment-aware locomotion intent recognition module. These models enable intelligent and adaptive control strategies for lower-limb exoskeletons during stair ambulation.
