Kaitai is currently a lecturer (assistant professor) at SCCS (which is one of the top 14 Academic Centres of Excellence in Cyber Security Research recognised by the UK Government Communications Headquarters in partnership with the Engineering and Physical Sciences Research Council) and Department of Computer Science, University of Surrey, U.K. His main research interests are applied cryptography, privacy and security in information technology; in particular, encryption, signature, blockchain security, cloud computing security, Internet of things, post-quantum crypto, privacy enhancing technology and lightweight secure system.
He has published over 60 research works with at least 1,5k citations, related to applied cryptography and information security in high tier (Q1 and top 3 of google scholar computer security and cryptography ranking) security international journals and conferences (e.g., IEEE TIFS, ESORICS). He also has prepared (proposal writing) and involved into five European projects (e.g., H2020, UK, Academic of Finland) as PI or CI. He has experience in collaborating with (projects, funding and research) international industries and companies, and in teaching undergraduate, master levels computer science courses and PhD supervision.
He received the Ph.D. degree in computer science (applied cryptography direction) at the Department of Computer Science, City University of Hong Kong, under the supervision of Duncan S. Wong (currently CEO of CryptoBLK) in October 2014. Before joining Surrey, he was a post-doctoral researcher and a lecturer, at Department of Computer Science, Aalto University, and School of Computing, Mathematics and Digital technology, Manchester Metropolitan University, respectively.
