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.

主动物质是指组合自行式单元，例如鸟类，鱼类，人类，细菌，无人机。这些单位倾向于在各种结构中进行自组织，而无需任何外部指导。例如，鸟类蜂拥而至。主动物质的敏捷性和多功能性（如《八哥》中所示）激发了科学家和工程师开发具有相似特性的材料。今年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的领域的最新进展。这是一个项目，旨在支持与美国年轻科学家和学生的注册和旅行有关的费用，以在2022年9月在Cargese（法国Corsica Island，France）举行的“活跃物质和复杂媒体”上的暑期学校上学。约有15位美国参与者（研究生和后学生）可以通过这项赠款来支持这些赠款，否则可以将这些赠款与他们的行动相关，可以派遣活动。活动能够参加活动。动作效果或能够进行活动。以不同的方式包装，为流体提供不同的宏观特性。暑期学校的重点将放在非常活跃的领域，包括微生物游泳，在复杂且拥挤的环境中（例如多孔媒体）中的机动胶体和主动颗粒的集体行为。拟议研讨会的目的是解决积极的（合成，仿生和生活）的建模中的挑战，讨论要克服这些挑战的方法，并教育和告知年轻科学家（主要是研究生），他们将不仅会在技术和基础上进行培训，而且还要介绍当前的研究界的精液，并从本地界撰写了本次知识，从本地进行了研究，这些领域及其在世界上及其领域的领域及其专业的专业专家，这些都是专家及其专家的专家。该会议具有较强的跨学科特征，涉及来自不同学科的研究人员（物理，工程，应用数学，生物学）以及不同的一代（专家高级科学家和学生）。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子和更广泛的影响来评估的支持，并被认为是值得的。
