长期从事无线与移动网络、天地一体化网络、智能边缘计算与网络安全的研究。研究重点关注移动网络系统的软件与体系架构，通过软件与架构创新让下一代移动网络系统更加智能、开放、可靠、快速与安全。主要研究成果已发表在国际顶级会议（SIGCOMM, MobiCom, NSDI, INFOCOM, CCS, SIGMETRICS）和期刊（ToN, TMC）30余篇，两次获得移动网络国际顶级会议MobiCom 最佳研究社群论文奖（Best Community Paper Award）。相关成果促成了开源4G/5G移动网络大数据平台MobileInsight，目前已被学术界和工业界广泛使用。部分成果已通过初创企业MobIQ Technologies实现成果转化。

近年来的主要研究成果包括

1.基于终端的移动网络大数据智能分析平台：开发了全球首个基于终端的4G/5G网络大数据开源系统MobileInsight，第一次赋予终端对移动网络行为的学习和推理能力。为了实现深度、细粒度的实时移动网络数据分析， MobileInsight通过软硬件协同，让现有的手机与IoT终端就可以实时访问硬件芯片内的全栈4G/5G数据。接着利用这些数据，设计了多种面向4G/5G的机器学习算法，为终端开启针对用户端和网络端行为的学习和推理能力。自2016年发布以来，MobileInsight已被260+高校和公司所使用，并于2016年荣获ACM MobiCom Best Community Paper Award（每年全球仅授予一篇在无线和移动系统领域提供开源平台的开创性贡献论文）；

2.利用移动网络大数据赋能智能终端应用：基于移动网络大数据，赋能新兴应用。不同的移动、IoT和边缘应用对网络可靠性、安全性和性能有不同要求。单纯依靠基础设施段的网络优化无法很好的感知和满足终端应用需求。为解决这一问题，开发了基于学习、应用驱动的移动网络定制方案。利用4G/5G网络大数据，基于终端应用的特定需求实现基于终端的网络服务定制。这一方案已经在不同的场景里进行了验证，例如低延迟VR/AR(SIGMETRICS’18)、可靠高铁网络(SIGCOMM’20, MobiCom’19, JSAC’20)、高性能Google Fi多网融合 (ToN’18, NSDI’16)、数据与语音安全（CCS’15, CCS‘16）等;

3.基于可验证技术简化移动网络基础架构:  利用终端智能帮助基础设施，实现简洁、可验证的移动网络服务。研究覆盖了数据面、控制面和管理面，包括低延迟网络（MobiCom’21, NSDI’21, MobiCom’17），网络信令协议验证(SIGCOMM’14, ToN’16)，网络配置和策略冲突管理（MobiCom’18, SIGMETRICS’16），基于动态博弈的可信网络计费(SIGCOMM’19)等。
