      <description>&lt;p&gt;IRIS 연구실 박사과정 졸업생인 정문찬(Cheng Wencan) 연구원이 2026년 4월부터 중국 Sun Yat-sen 대학교(Sun Yat-sen University) 인공지능학과 교수로 임용됩니다.&lt;/p&gt;
&lt;p&gt;정문찬 박사는 성균관대학교에서 박사학위를 취득한 후, 싱가포르국립대학교(National University of Singapore, NUS)에서 박사후연구원으로 활동하며 효율적인 하드웨어 및 3D 구조 데이터 처리 연구를 수행해왔습니다.&lt;/p&gt;
&lt;p&gt;IRIS 연구실에서 정문찬 박사는 3D 손 자세 추정, 포인트 클라우드 기반 장면 흐름 추정, FPGA 기반 실시간 시스템 등 다양한 연구 성과를 이루었으며, IEEE IoT Journal을 비롯한 저명한 학술지와 CVPR, ICCV 등 최고 수준의 국제 학회에 다수의 논문을 발표했습니다.&lt;/p&gt;
&lt;p&gt;주요 연구 업적으로는 Diffusion 모델을 활용한 3D 손 자세 추정(HandDiff), 적응형 그래프 트랜스포머 기반 노이즈 제거 기법(HandDAGT), 간접 ToF 센서를 위한 FPGA 기반 에너지 효율적 실시간 시스템 등이 있으며, 이러한 연구들은 효율적인 3D 비전 시스템 구현에 중요한 기여를 했습니다.&lt;/p&gt;
&lt;p&gt;IRIS 연구실은 정문찬 박사의 교수 임용을 진심으로 축하하며, 앞으로 Sun Yat-sen 대학교에서 인공지능 분야의 우수한 연구자와 교육자로서 더욱 발전하기를 기원합니다.&lt;/p&gt;
&lt;p&gt;IRIS Lab is delighted to announce that Dr. Cheng Wencan (정문찬), a distinguished Ph.D. graduate from our laboratory, has been appointed as a Professor in the Department of Artificial Intelligence at Sun Yat-sen University, effective April 2026.&lt;/p&gt;
&lt;p&gt;After completing his Ph.D. at Sungkyunkwan University, Dr. Cheng served as a Postdoctoral Researcher at the National University of Singapore (NUS), where he conducted research on efficient hardware and 3D structural data processing.&lt;/p&gt;
&lt;p&gt;During his time at IRIS Lab, Dr. Cheng made significant contributions to various research areas, including 3D hand pose estimation, point cloud-based scene flow estimation, and FPGA-based real-time systems. His work has been published in prestigious journals such as the IEEE IoT Journal and presented at top-tier international conferences including CVPR and ICCV.&lt;/p&gt;
&lt;p&gt;His notable research achievements include HandDiff (3D hand pose estimation using diffusion models), HandDAGT (denoising with adaptive graph transformers), and an FPGA-based energy-efficient real-time system for indirect ToF sensors. These contributions have significantly advanced the field of efficient 3D vision systems.&lt;/p&gt;
&lt;p&gt;IRIS Lab extends its warmest congratulations to Dr. Cheng Wencan on his faculty appointment and wishes him continued success as a leading researcher and educator in artificial intelligence at Sun Yat-sen University.&lt;/p&gt;
