Biographical Sketch

Tat-Jen is an Associate Professor in the School of Computer Engineering, Nanyang Technological University, and Director of the Centre for Multimedia & Network Technology (CeMNet). He received his BA in Engineering with triple first class honours in 1993 and his PhD in 1996, both from the University of Cambridge, during which he was awarded the Loke Cheng-Kim Foundation Scholarship, the Alexandria Prize, the Engineering Members’ Prize as well as the St Catharine’s College Senior and Research Scholarships. Tat-Jen was subsequently conferred a Jesus College Research Fellowship in Science in 1996-97. From 1998 to 2001, he was a research scientist at DEC/Compaq CRL in Cambridge, MA, USA, where his experience included technology transfer to product groups and showcasing research work to Hollywood studios. After joining NTU in 2002, he was concurrently a Faculty Fellow in the Singapore-MIT Alliance Computer Science Program in 2003-2006.

Tat-Jen’s research interests are broadly in computer vision and sentient environments. In the area of computer vision, his main research topics are machine-learned object matching and registration, human tracking as well as activity recognition in video. In the area of sentient environments, he is working on systems that synergistically combine projectors and cameras to turn all surfaces into ubiquitous interactive displays. For his research, Tat-Jen received overall best paper prizes at PROCAMS’05, BMVC’94, and in particular at ECCV'96 (now known as the Longuet-Higgins prize), while his PhD student Minh-Tri Pham was awarded the PREMIA 2nd best student paper prize for their ICCV'2007 paper. Tat-Jen's research work has consistently appeared in the top publication venues for computer vision, and has been cited over 1000 times. In 2007, Minh-Tri and Tat-Jen were one of only two first-second author pairings in the world to be awarded two prestigious oral presentations in CVPR’2007 and ICCV’2007. Tat-Jen is an inventor on eight patents, and his team’s open source software PyCV, incorporating the world's fastest method for training an Adaboost cascade face detector, was downloaded over 2000 times within two months of release. Since 2002, he has received over S$2M in research grant funding, from the Defence Science & Technology Agency, the Singapore-MIT Alliance and the Ministry of Education.

Tat-Jen is on the editorial board for IJCV and is an Area Chair for ICCV'09, the top journal and conference in his field respectively. He is/was also an Associate Editor for IJIG and IPSJ-CVA, an Area Chair for ICCV'05, ACCV'06 and ACCV’07, a Program Chair for MMM’07, and a co-founder for the well-established PROCAMS workshop series started in 2003. Locally, he is/was on the A*STAR SERC PSF grant selection and review panels, the I2R-University Joint-Lab review panel, the NRF/MDA IDM i.ROCK proposal shortlist panel, a co-convener of the A*STAR TSRP on UWB & Pervasive Computing.

Tat-Jen's lecture courses included pervasive human-centric computing, a jointly-taught SMA graduate module resulting in game-related student projects that received substantial media coverage from Channel News Asia, Lian He Zao Bao and Tamil Murasu in June 2004.
