“…Prof. Hao published about 50 peer-reviewed papers in this field, which mostly involve the development of algorithms, software tools, and web servers. His best-acknowledged contribution to the field is his genome sequence analysis tools and analyses for prokaryotic genomes, such as CVTree [2], [3], [4], [5], [6], [7] (http://www.itp.ac.cn/~hao/). All his publications are thoroughly recorded in Mrs. Zhang’s book [1], except his latest article published in this issue, which he had been working on until this March [8].…”
