2021年5月31日、6月2日及6月4日，美国休斯敦大学教授韩竹与通信工程学院师生进行了为期3天的线上学术交流活动，讲座由教授胡封晔主持，我院师生分别通过线上平台及线下分会场参加本次系列讲座，累计近一百五十人参会。
教授韩竹此次围绕三个专题做系列学术报告，主题分别为“metasensing: reconfigurable intelligent surface assisted rf 3d sensing using machine learning”，“secure computation with privacy preservation for cyber physical system applications”，和“mean field game tutorial and examples”。
韩竹首先介绍了6g通信的基本知识及reconfigurable intelligent surface (ris) 技术的基础和潜在应用。然后讲述了ris辅助射频传感与定位系统，通过对三个案例的分享讨论，突出ris的独特功能，深入讨论ris未来发展方向的可能性。
随后的讲座中，韩竹对cyber physical systems（cps）即信息物理系统进行了介绍。通过将安全/隐私保护与各种信息物理融合建模相结合进一步介绍了跨学科研究工作的研究方向，其中分别对基于下行时钟拍卖的数据中心应急需求响应、智能家居中成本感知设备调度的admm方法、生理传感器机器学习的微分私有优化进行了详细讲解，表达了安全和隐私保护对于建立高度信任和安全的客户服务系统的重要意义。
最后，韩竹在讲座中阐述了平均场博弈理论的基本框架和研究方案，以介绍多种理论为例全面演示如何使用他们来解决实际问题，并总结相关结论，指出当前研究所存在的局限性与未来发展方向。
韩竹针对无线通信前沿技术进行了十分精彩的学术报告，会上讨论气氛浓烈，线上线下同步进行。师生踊跃提问，韩竹耐心一一进行了解答。通过本次系列线上学术活动，同学们不仅开拓了在无线通信方面的视野，更从他的报告中获得了很大的启发。
