Professor Bo Jin got his doctor degree in 1998, after that, he become a faculty of the department of mechanical engineering in Zhejiang University. His research areas mainly about electro-hydraulic control system and mechatronic control system in deep sea. In the research area of electro-hydraulic control system, a new vary speed electro-hydraulic control system based on energy regulating strategy is figured out, which can not only improve the dynamic response and control accuracy of vary speed electro-hydraulic control system(using frequency inverter to control the pump speed) significantly, but also obtain efficiency like pump control system. In the research area of mechatronic control system in deep sea, by applying the static pressure equilibrium principle to the fluid control system of deep-sea in-situ chemical sensors, the world’s first prototype of in-situ chemical sensor with self-calibrating is figured out, with low power consumption design, it had been uses in long-term in-situ monitoring of the hydrothermal fluid. More than Seventy papers were published on journals, magazines and conference both in China and abroad. Among them, twenty papers is indexed by SCI, thirty papers are indexed by EI. Thirteen national patents ofChinaawarded.  As major participator, he won one National Second Prize of Science and Technology, two Provincial/Ministerial First Prizes of Science and Technology and two Provincial Third Prizes of Science and Technology. As chief scientist, he undertook one project of National Natural Science Foundation of China, one subproject of Key project of National Natural Science Foundation of China, six projects of HI-TECH Research and Development program of China.
