Personal profile

Academic background

Dr. Kaitai Liang joined the Cybersecurity group at Delft University of Technology in 2020. Before joining TU Delft, he was an Assistant Professor in Secure Systems at the University of Surrey, UK, and an academic member of the Surrey Centre for Cyber Security. He received his PhD degree in computer science from City University of Hong Kong. His main focus is on the design and implementation of cryptographic protocols to security. He has involved (as PI and CI) in several European funded projects and H2020 proposals, e.g., ASSURED, SPEAR, SECONDO, CUREX, Academic of Finland, and delivered real-world impact via these projects with his academic (e.g., University of Birmingham, University of Luxemburg) and industrial partners (e.g., IBM, Huawei Germany, Infineon). He has also maintained a tight and strong research relationships with Europe, Asia-pacific and northern America academic communities. He has published a series of research works (over 80 publications, more than 2,000 citations), applying information security and crypto tools to tackle real-world problems, in many high tier international journals and conferences, in particular in the Computer Security & Crytography top venues (https://scholar.google.es/citations?view_op=top_venues&hl=en&vq=eng_computersecuritycryptography), e.g., IEEE TIFS, IEEE NETWORK, IEEE Transactions on Industrial Informatics, ESORICS. He has served as technical program committee for over 25 renowned international security/privacy conferences, e.g., ESORICS, ACNS, TRUSTCOM, ASIACCS. He has contributed to ISO standard being an official ISO member of ISO Crypto Sub Committee IST/33/2. In addition to being active reviewers for many international journals/conferences, he also serves as associate editor, e.g., for the Computer Journal, guest editor, e.g., for IEEE Transactions on industrial informatics, and cybersecurity consultant for SMEs.
