A brief bio:
Prof. X. San Liang received his Ph.D. in Applied Mathematics from Harvard University, USA. He did his postdoctoral work at Harvard, and has held positions at different institutions and organizations in China and USA, such as the Second Institute of the State Oceanic Administration, the ninth Chinese Antarctic Research Expedition (CHINARE), Stanford University-NASA Ames Research Laboratory (Visiting Scholar), Massachusetts Institute of Technology (Scientist), Courant Institute of Mathematical Sciences (Scientist; Principal Scientist since '07), China Institute for Advanced Study (Professor of Natural Science), etc. Currently he is Jiangsu Chair Professor of Atmosphere-Ocean Science at Nanjing University of Information Science and Technology.
• New mathematical machinery (multiscale window transform) invented for multiscale research.
• Systematic contribution on multiscale geophysical fluid dynamics, including mean-eddy-turbulence interaction, canonical transfer, localized hydrodynamic stability, etc., for the understanding, quantification, and control of the complex internal nonlinear dynamical processes within realistic ocean/atmosphere flows and the emergence of coherent structures on different scales.
• Systematic contribution on information flow (and predictability, causality, etc.), a fundamental notion in general physics which has applications in a wide variety of disciplines such as ocean-atmosphere science, turbulence, neuroscience, material science, network studies, economics, to name but a few.
• Trained in both science and engineering. Strong multidisciplinary background in atmosphere-ocean science, applied mathematics, and engineering science.
• Extensive experience of numerical simulation; a hierarchy of ocean models built since 90s.
• Three years of sea-going survey experience; half a year of Antarctic adventure.
Current Research Interests:
Multiscale geophysical fluid dynamics, Multiscale modeling and simulation, Atmospheric and oceanic predictability, Information flow, Causality analysis, Climate dynamics (ENSO & NAO), Chaotic mixing, Atmospheric cyclogenesis, Ocean eddy shedding, Hydrodynamic instability, etc.
