This Faculty Early Career Development (CAREER) award supports research that will enable new understanding of the swimming mechanics of bottlenose dolphins. Researchers will gather information on the behavior of free-swimming bottlenose dolphins using electronic tags that are attached to the animal and that measure both movement and caloric expenditure. The collected information, combined with mathematical modeling, will lead to new understanding of dolphin swimming. Such an understanding is critical to policy and management practices that reduce the impact of human activities on these animals. This research will be integrated with education and outreach activities that are designed to inspire a new and diverse generation of students and engineers and to raise awareness of the social and environmental implications of bio-inspired engineered systems.This project will advance the current state of knowledge of the swimming mechanics of bottlenose dolphins by creating a novel diagnostic framework that will combine low-order mathematical models of swimming with kinematic data from biologging tags. The framework will lead to a fundamental scientific understanding of the impact of biomechanical parameters, like fluke flexibility and swimming gait, on the cost of locomotion. Importantly, this new bio-logging paradigm will enable us to obtain, using single-point kinematic measurements taken from free-swimming animals, estimates of the mechanical cost of swimming. This work will produce first-of-their-kind estimates of the energetic cost during free swimming. The new knowledge developed over the course of this project will impact the fields of biologging, biomechanics, and the modeling of dynamical systems.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该学院早期职业发展（CAREER）奖支持研究，使人们对宽吻海豚的游泳机制有了新的认识。研究人员将使用附着在动物身上并测量运动和热量消耗的电子标签来收集有关自由游泳的宽吻海豚行为的信息。收集到的信息与数学模型相结合，将带来对海豚游泳的新认识。这种理解对于减少人类活动对这些动物的影响的政策和管理实践至关重要。这项研究将与教育和外展活动相结合，旨在激励新一代多样化的学生和工程师，并提高人们对仿生工程系统的社会和环境影响的认识。该项目将通过创建一个新颖的诊断框架，将游泳的低阶数学模型与生物记录标签的运动学数据相结合，从而推进对宽吻海豚游泳力学的了解。该框架将使人们对生物力学参数（如侥幸灵活性和游泳步态）对运动成本的影响有一个基本的科学理解。重要的是，这种新的生物记录范式将使我们能够利用自由游泳动物的单点运动学测量来估计游泳的机械成本。这项工作将对自由游泳期间的能量消耗进行首次估计。该项目过程中开发的新知识将影响生物记录、生物力学和动力系统建模领域。该​​奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
