主要研究方向包含移動機器學習，物聯網感知及安全，人機交互及安全。

研究主要緻力于在物聯網/移動設備/可穿戴設備/XR設備上結合機器學習/深度學習/大模型技術與信号設計/分析/處理方法，以實現面向未來化的感知/交互應用，同時揭示其中潛在的安全性問題。除了軟件層面的算法設計，研究工作也非常關注于系統實現和實際場景驗證，研究成果與上海評駕科技有限公司，螞蟻集團，OPPO公司等均有合作落地。

歡迎對我研究方向有濃厚興趣，動手能力強的同學加入我的科研團隊攻讀碩士研究生和博士研究生（目前25年入學的博士研究生和26年入學的碩士研究生可聯系）（與淩振教授共同指導）！也歡迎Self-motivated的本科生聯系，進行科研、競賽訓練。(郵件：xy-xu@seu.edu.cn)
