My name is Jian Guo, I am currently Senior Research Scientist and Principal Investigator with Temasek Laboratories at Nanyang Technological University in Singapore, leading the Cryptanalysis Taskforce team. My research interests focus on symmetric key cryptography, especially cryptanalysis, design and implementation of (lightweight) hash functions, block ciphers, authenticated encryption schemes, and their applications such as message authentication codes.
