Guo Jian received his B. Eng with First class honors from SCE, and PhD from SPMS NTU in 2007 and 2011, respectively. He then worked with Institute for Infocomm Research in Singapore for 2.5 years, and returned to NTU as a postdoctoral research fellow in 2013. He subsequently joined Temasek Labs as a Principal Investigator and SPMS as an Assistant Professor.

His major research interest is symmetric-key cryptography, including cryptanalysis, design and implementation of (lightweight) hash functions, block ciphers, authenticated encryption schemes, and their applications such as message authentication codes. Among others, he published 30+ papers in top conferences and journal under the International Association for Cryptologic Research, which received 2000+ citations according to Google Scholar.

He is founding co-chair of ASK --- Asian workshop on Symmetric-Key cryptography: He served/will serve as general (co-)chair of FSE 2013 and ASIACRYPT 2021, program committee members of FSE 2017, 2018, 2019, 2021, ASIACRYPT 2017, 2019, 2020, and EUROCRYPT 2018, 2020 etc, and reviewer for all major cryptography conferences and journals. He gave an invited talk on the cryptanalysis of SHA-3 at FSE 2019. He is a member of ASIACRYPT steering committee representing for Singapore, and also a member of the Security and Privacy Standards Technical Committee acting as Singapore delegate of the International Standardization ISO/IEC JTC 1/SC 27. He has been leading the Cryptanalysis Taskforce research team at NTU:
