Présentation
Lu ZHANG is an associate professor (in french, “maître de conférences”) in the « Industrial computer science and electronics » department of the « National Institute of Applied Sciences (INSA) of Rennes » in France.
She received the B.S degree from Southeast University and the M.S. degree from Shanghai Jiaotong University in China in 2004 and 2007, respectively. During her master studies, she worked on video coding and image processing. Then she participated in the Engineering Leadership Program (ELP) of National Instruments (NI) at Shanghai. From October 2009 to November 2012, she was a PhD student of the LISA and CNRS IRCCyN labs in France, working on the model observers for the medical image quality assessment. Then she participated in an European Space Agency (ESA) project and worked on the quality of experience (QoE) in telemedicine, before she joined INSA Rennes and the VAADER research team of the IETR lab in September 2013.
ince then, she has co-supervised 14 PhD students who have successfully obtained their doctoral degrees, as well as 3 postdocs, and she is currently co-supervising 2 PhD students. Since 2019, she has been the coordinator of the “Embedded and Connected Artificial Intelligence” Transversal Program at the IETR laboratory, and since September 2023 she has been head of the VAADER team at IETR. She has served as a PhD thesis defense jury member 14 times, including nine times as rapportrice in France, once in Belgium, and once in Spain.
She is a board member of the international Video Quality Experts Group (VQEG), where she co-chairs two working groups. She was elected as a member of the IEEE Multimedia Signal Processing Technical Committee (MMSP TC) and the EURASIP Technical Area Committee on Visual Information Processing (VIP) for the 2022–2027 term. She serves on the organizing committees of numerous international conferences, co-chairing program, website, awards, special sessions, challenge, plenary, and student/young professional tracks (e.g. ICME, ICIP, MMSP, PCS, EUVIP). She has also organized special sessions and workshops at international conferences such as QoMEX, EUSIPCO, and ACM IMX, and organized the French Journée GDR-IASIS in 2024 and hosted the Spring 2022 VQEG meeting. She is also an Associate Editor for the international journals IEEE Transactions on Multimedia, EURASIP Journal on Image and Video Processing, and Displays (Elsevier).
