Sujet de recherche
Li Weng received his PhD in electrical engineering from KU Leuven (Belgium) in 2012. He worked on encryption, authentication, and hash algorithms for multimedia data. He then worked at University of Geneva (Switzerland) and Inria (France) on large-scale content-based information retrieval systems with emphasis on privacy protection. He is currently a post-doctoral researcher at IGN - French Mapping Agency. His research interests include signal processing, machine learning, and information security.
