I am an Assistant Professor at Xiamen University Malaysia. My work lies at the intersection of biometrics, computer vision, and cryptography, with a focus on flexible and privacy-aware biometric recognition. I am particularly interested in systems that remain reliable under practical conditions such as occlusion, modality mismatch, low image quality, and real-world deployment constraints. 저는 샤먼대학교 말레이시아캠퍼스의 조교수입니다. 생체인식, 컴퓨터 비전 및 암호학의 접점에서 연구하며, 유연하고 프라이버시를 고려한 생체인식에 중점을 두고 있습니다. 특히 가림, 모달리티 불일치, 낮은 영상 품질 및 실제 배포 제약과 같은 현실적인 조건에서도 안정적으로 동작하는 시스템에 관심이 있습니다. 厦門大学マレーシア校の助教として、生体認証、コンピュータビジョン、暗号学の接点に取り組んでいます。柔軟性とプライバシーを考慮した生体認証を中心に、遮蔽、モダリティ不一致、低画質、実環境での展開制約といった条件下でも安定して機能するシステムに関心があります。 我是厦门大学马来西亚分校的助理教授,研究位于生物识别、计算机视觉与密码学的交叉领域,重点关注灵活且注重隐私的生物识别方法。我尤其关注在遮挡、模态不匹配、低图像质量以及实际部署限制等条件下仍能保持可靠性的系统。
I received my Doctorate in Engineering from Yonsei University, where my doctoral research focused on conditional periocular-face biometrics for flexible deployment. My broader interests include representation learning, biometric template protection, multimodal learning, and provable security. Alongside research, I teach and supervise undergraduate and postgraduate students in computing and cybersecurity-related areas. 연세대학교에서 공학 박사 학위를 받았으며, 박사 연구에서는 유연한 배포를 위한 조건부 눈 주위-얼굴 생체인식에 중점을 두었습니다. 보다 넓은 관심 분야는 표현 학습, 생체 템플릿 보호, 멀티모달 학습 및 증명 가능한 보안을 포함합니다. 연구와 함께 컴퓨팅 및 사이버보안 관련 분야에서 학부 및 대학원 학생을 가르치고 지도하고 있습니다. 延世大学校で工学博士号を取得し、博士研究では柔軟な展開を目的とした条件付き眼周囲・顔生体認証に取り組みました。より広い関心には、表現学習、生体テンプレート保護、マルチモーダル学習、証明可能安全性が含まれます。研究と並行して、コンピューティングおよびサイバーセキュリティ関連分野で学部・大学院教育と研究指導を行っています。 我在延世大学获得工学博士学位,博士研究聚焦于面向灵活部署的条件性眼周-人脸生物识别。更广泛的研究兴趣包括表征学习、生物模板保护、多模态学习与可证明安全性。同时,我也负责计算与网络安全相关领域的本科与研究生教学及研究指导。
