Daoyuan Wu is a Research Assistant Professor in the Department of Information Engineering at the Chinese University of Hong Kong (CUHK) since August 2019. Prior to CUHK, Daoyuan earned his PhD degree from Singapore Management University (SMU) in the School of Information Systems. Before pursuing his PhD in Singapore, Daoyuan received the M.Phil. from The Hong Kong Polytechnic University in 2015, and B.E. from Nanjing University of Posts and Telecommunications in 2011.

Daoyuan is broadly interested in system and network security, with a focus on the vulnerability and privacy research. His major research methodology includes program analysis, network measurement, and data mining or analytics. In particular, Daoyuan is one of the pioneers in using on-device app crowdsourcing for security and networking research. He is also an expert in developing practical Android static analysis, for which he is leading a long-term project on using search-based static analysis for Android security. Besides publishing papers in top-tier venues (e.g., NDSS and ATC), he has reported many app vulnerabilities on both Android and iOS (over 60 CVEs), as well as one system issue in Android (CVE-2014-7224) and one in iOS (CVE-2015-5921).
