My name is Jian Guo, I am currently working
 with the School of Physical and Mathematical Sciences of 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.
