1. Actual employment

2019 – current: Research Engineer, full-time permanent, Laboratory Movement, Interactions, Performance, UR4334, Nantes Université, Nantes, France

• Research activity: o Human Performance: Study of neuromuscular mechanisms in music and professional contexts. Current projects: -- Drums Biomech: Biomechanical study of double-bass techniques in drumming, using tools such as motion capture, ultrasound and electromyography. -- Surgical Fatigue: Analysis of fatigue impact on gynecological surgeons’ performance, using biomechanical and cognitive measurements. o Neuromuscular Disorders: Applied research on muscle adaptations following pathologies like cerebral palsy or stroke. Current project: -- Muscle Lengths and Pathologies: Assessment of muscle lengths using 3D ultrasound in patients with bone deformities.

• Methodological development: Advanced biomechanical and imaging techniques (high-density electromyography, 3D ultrasound, shear wave elastography).

3. Teaching, student supervision and outreach activities

• Course leader for "Data Processing and Management", UFR STAPS, Nantes University. • Supervision of Master’s students on biomechanical and clinical topics (n=6). • Organization of public science events (e.g., Researchers’ Night) and contribution to science podcasts.

4. Development in relation to 3D Ultrasound

Aurélie Sarcher is the Principal Investigator of the OPTIMUS project : Open-Platform for Three-dimensional Imaging of Muscle using UltraSound. She has developed innovative methodologies for 3D freehand ultrasound imaging, leveraging existing open-source solutions. Her expertise spans system integration, from configuring hardware setups to creating user-friendly protocols for research and clinical applications. She has applied these techniques to investigate muscle-tendon unit lengths, and muscle volumes and shapes in sarcopenia and neuromuscular pathologies in clinical populations. Her work has supported international collaborations with renowned institutions (KU Leuven, Norwegian School of Sport Sciences, and others) and contributed to creating accessible educational resources shared via platforms like GitHub.
