Active matter refers to collectives of self-propelled units, e.g., birds, fish, humans, bacteria, drones. The units tend to self-organize in various structures, without any external guidance. For example, birds flock and bacteria swarm. The agility and versatility of active matter (as seen in the starling murmurations) is inspiring scientists and engineers to develop materials with similar properties. This summer school will introduce graduate students and post-doctoral researchers to the latest advances in this rapidly evolving field. This is a project to support expenses related to the registration and travel of young scientists and students from the US to attend the summer school on " Active Matter and Complex Media" to be held in Cargese (Corsica Island, France) in September 2022. About 15 US participants (graduate students and post-docs) are expected to be supported through this grant, who would not otherwise be able to attend.Active fluids are those where the presence of active particles that can self-assemble, or can move and pack in different ways, give different macroscopic properties to the fluid. The focus of the summer school will be on areas that are very research active, including microorganism swimming, collective behavior of motile colloids and active particles in complex and crowded environment (such as porous media). The aims of the proposed workshop are to address challenges in the modeling of active (synthetic, biomimetic, and living) matter, to discuss approaches to overcome these challenges, and to educate and inform young scientists (mainly graduate students), who will be attending not only lectures on techniques and fundamentals, but also seminars on current research topics given by internationally known experts in the field, from the US and from around the world. The conference has a strong interdisciplinary character involving researchers from different disciplines (physics, engineering, applied mathematics, biology) as well as different generations (expert senior scientists and students).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.

活性物质是指自驱动单位的集合，例如鸟类、鱼类、人类、细菌、无人机。这些单位倾向于以各种结构自组织，无需任何外部指导。例如，鸟类成群，细菌成群。活性物质的灵活性和多功能性（如八哥的低语中所见）正在激励科学家和工程师开发具有类似特性的材料。这个暑期学校将向研究生和博士后研究人员介绍这个快速发展领域的最新进展。该项目旨在资助来自美国的年轻科学家和学生参加将于 2022 年 9 月在卡尔热斯（法国科西嘉岛）举办的“活性物质和复杂介质”暑期学校的注册和旅行费用。 15 名美国参与者（研究生和博士后）预计将通过这项资助获得支持，否则他们将无法参加。活性流体是指那些存在可以自组装或可以移动和堆积的活性颗粒的流体以不同的方式，给予流体的宏观性质不同。暑期学校的重点将放在研究非常活跃的领域，包括微生物游泳、运动胶体和活性颗粒在复杂和拥挤的环境（例如多孔介质）中的集体行为。拟议研讨会的目的是解决活性（合成、仿生和活体）物质建模中的挑战，讨论克服这些挑战的方法，并对将参加的年轻科学家（主要是研究生）进行教育和告知不仅有技术和基础知识讲座，还有来自美国和世界各地的该领域国际知名专家就当前研究主题举办的研讨会。该会议具有很强的跨学科性质，涉及不同学科（物理学、工程学、应用数学、生物学）以及不同代际（专家资深科学家和学生）的研究人员。该奖项体现了NSF的法定使命，经评估认为值得支持利用基金会的智力优势和更广泛的影响审查标准。
