Professor Jong-Ho Lee's research lab specializes in the intersection of biomedical engineering and neuroscience, focusing on the quantitative analysis of movement disorders in neurological patients. The lab employs surface EMG and kinematic data to investigate motor control deficits in conditions such as Parkinson’s disease and cerebellar ataxia, aiming to extract objective biomarkers from motor command-level signals. In parallel, the lab explores advanced materials for energy applications, particularly fast-ion conducting solid electrolytes for all-solid-state lithium batteries. The research integrates signal processing, clinical neurology, and materials science to develop diagnostic tools and next-generation energy materials.

In this paper, we propose a new method to make a quantitative evaluation for movement disorders. Based on the EMG signals, we analyzed the movement disorders for cerebellar patients at the motor command level. As an experimental task, we asked subjects to perform step-tracking wrist movements with a manipulandum, and simultaneously recorded wrist joint movements and muscle activities of four wrist prime movers with surface electrodes. In order to quantitatively evaluate the correspondence betwee
In this study, we extracted feature parameter for movement disorders of neurological patients using a wrist movement. Specially, based on EMG signals, we captured feature patterns of movement disorders for Parkinson’s patients and cerebellar patients from the motor commands level. As an experimental task, we asked subjects to perform smooth pursuit wrist movement, in which the subjects follow a smoothly moving target with a cursor. We recorded movement of the wrist joint and EMG signals of four
A fast Li-ion conducting I-rich argyrodites with excellent stability with Li metal was successfully demonstrated by a controlled mechanical alloying method.
