My research career is focused on improving the utility of human movement data by creating innovative engineering tools for its analysis, classification and interpretation. Working with my students, and supported by Discovery Grant funding, my research has contributed significantly to the development of classification tools to detect differences in movement patterns and computational models to give these differences physical meaning. In addition to improving applied science, these tools have provided insight into the fundamental processes underlying a given movement pattern. The influence of this work is evident by the uptake of these methods in human movement research; however, there remains large barriers to the integration of human movement data in applied research and practical applications. Identifying and resolving these barriers is what currently motivates me and where the target of my current and future research has been set. Markerless motion capture is an emerging technology for estimating the 3D position and orientation (pose) of a human multibody model. Data can now be instantly collected anywhere that video cameras can record the subject, while virtually eliminating preparation time for the subject. There is no contact between the subject and the researcher, and subjects' data are collected while wearing their own clothing, removing the barrier of requiring minimal tight fitting clothing for research. To fully realize the potential of markerless motion capture and to take advantage of the new flexibility in raw data, the focus of my research program will be developing the next generation of biomechanical analysis tools. Increasing the automation of human movement data collection as a result of the adoption of computer vision and machine learning will substantially increase our ability to generate high quality data at volume in a fraction of the time for a fraction of the cost. Large scale, longitudinal data collections that have never before been possible in biomechanics due to the many limitations of existing technology will become achievable. We are developing tools that can assess movement throughout the natural environment. Eliminating unnecessary physical proximity through a completely contactless approach to biomechanical data collection is a significant advantage and will help researchers recruit a more diverse group of subjects because it overcomes many barriers to participation, including eliminating the need for minimalistic tight-fitting clothing, and the travel required to get to a motion laboratory. This work may finally allow the adoption of biomechanical tools into wider use, improving the study of clinical movement disorders, musculoskeletal diseases, injuries, and athletic performance.

我的研究职业专注于通过创建创新的工程工具来分析，分类和解释来改善人类运动数据的实用性。与我的学生合作，并在发现赠款资金的支持下，我的研究为分类工具的开发做出了重大贡献，以检测运动模式和计算模型的差异，以赋予这些差异。除了改进应用科学外，这些工具还深入了解了给定运动模式的基本过程。这些方法在人类运动研究中的吸收很明显。但是，在应用研究和实际应用中，人类运动数据整合的障碍仍然很大。确定和解决这些障碍是目前激励我以及我当前和未来研究的目标的原因。无标记运动捕获是一种估计人类多体模型的3D位置和方向（姿势）的新兴技术。现在，可以立即收集数据摄像机可以记录主题的任何地方，同时实际上消除了该主题的准备时间。受试者与研究人员之间没有接触，并且在穿着自己的衣服时收集了受试者的数据，从而消除了需要最小的紧身衣服进行研究的障碍。为了充分实现无标记运动捕获的潜力并利用原始数据中的新灵活性，我的研究计划的重点将是开发下一代生物力学分析工具。 由于采用了计算机视觉和机器学习，增加人类运动数据收集的自动化将大大提高我们在一小部分时间内以一小部分成本生成高质量数据的能力。由于现有技术的许多局限性，在生物力学上从未实现的大规模纵向数据收集将变得可以实现。我们正在开发可以评估整个自然环境运动的工具。通过完全不接触的生物力学数据收集来消除不必要的身体邻近性是一个重要优势，将有助于研究人员招募更多样化的受试者，因为它克服了许多参与的障碍，包括消除对极简主义紧身服装的需求，以及需要进行运动实验室所需的旅行。这项工作最终可能允许将生物力学工具用于更广泛的使用，从而改善临床运动障碍，肌肉骨骼疾病，伤害和运动表现的研究。
