网络安全，包括：网络流量分析、路由安全、网络威胁发现等

       长期从事网络安全相关研究，主要包括网络威胁发现、网络流量分析、路由安全等，发表相关论文30余篇，包括USENIX Security、ACM CCS、NDSS、IEEE INFOCOM、IEEE ToN、IEEE TIFS等网络与安全领域CCF-A类会议和期刊；曾获得2021年ACM SIGSAC China 优博奖（全国仅2人）、2021年清华大学“水木学者”、USENIX协会Student Travel Grant、EAI SecureComm Best Paper Award（大陆高校作为第一单位首次获该奖）等奖励。
近期主要研究方向如下：
1. 网络流量分析：针对互联网中的海量网络流量，依托人工智能和高性能网络等新技术，研究精准高效的流量分析方法，实现恶意流量识别、主机指纹追踪等安全相关任务。
2. 互联网路由安全：针对互联网域间路由存在的路由劫持、路由泄露等安全问题，研究数据驱动的路由威胁检测方法，以及设计新型的安全路由体系。
3. 网络威胁发现：针对网络架构与网络协议，研究揭露相关的安全威胁和攻击面，设计相应的防御方案。
