Studying the Neural and Mechanical Mechanisms of Human Movements
The UMD Neuromechanics Research Core studies neural and mechanical mechanisms of human movements in general. The current research focus includes locomotion in persons with lower extremity amputations and footwear, hand and multi-digit actions of people with neurological disorders, and sensory processing mechanisms.
The Core is equipped for biomechanical and physiological testing and analysis for human movements such as 11 Kistler force platforms, 23 Vicon motion capture cameras, electromyography sensors, movement speed sensors, electromagnetic sensors, a Biodex dynamometer, portable and stationary metabolic units, miniature 6-D force/torque sensors, etc. in over 7,000 sq ft space.
Graduate Student Opportunities
The Neuromechanics Research Core at University of Maryland is looking for highly motivated Ph.D. and Masters students interested in studying (1) biomechanics and motor control of hand and finger and (2) biomechanics and physiology of amputee running. The student will be supported by a research assistantship (RA) or a teaching assistantship (TA). Potential candidates are encouraged to send their CV's to Dr. Jae Kun Shim (email@example.com) as early as possible.
A student will develop a coherent area of expertise in human movement science by designing an academic program that includes introductory and advanced graduate courses in biomechanics, motor control, engineering, neuroscience, cognitive science, etc. A student can apply for a program of her/his background and interest in the Department of Kinesiology (Master's and PhD), Bioengineering Graduate Program (PhD), and Neuroscience and Cognitive Science (PhD).
Applications for admission should be received by January 15th. The following criteria will be considered for admission:
The main considerations for admission are: (a) the course background of the student (courses taken and/or experiences in Physics, Mechanics, Mathematics, Neuroscience, Computer Science, Anatomy, Physiology, Biomechanics, Motor Control, etc.); (b) the student's scores of all three GRE sections, and (c) the student's record of interest and/or academic performance in human movement sciences. LabView and MatLab, as well as experience in biomechanical and neurophysiological measurements and backgrounds in the control of human motion would be advantageous. Students from engineering and biological sciences are encouraged to apply. International students are required to demonstrate proficiency in English (TOEFL).

Our research is currently focused on:
- Locomotion in persons with lower extremity amputations.
- Neuromechanics of hand and multi-digit actions as well as their applications to medicine, rehabilitation, and ergonomics.
- CNS control mechanisms for motor redundancy, developments of motor functions in typically developing children as well as children with developmental coordination disorder, and developmental changes and intervention & adaptation of motor functions in elderly persons and the persons with neurological/genetic disorders or stroke.
- Gait (walking, running, sprinting) and related tasks (e.g. side-cutting) with long term objectives of: a) developing theories that explain and accurately predict the mechanics and energetics of human locomotion, and b) integrating principles from engineering, physiology, and neuroscience for early identification and prevention of locomotor impairments.
