I-Ming Chou is a distinguished research fellow at the Chinese Academy of Sciences (CAS). He received his B.S. degree from the Taiwan University (1968), Ph.D. degree from the Johns Hopkins University (1974). In 2013, after 33 years of service, he retired from the U.S. Geological Survey and was appointed as the director of the Lab for Experimental Study under Deep-sea Extreme Conditions in the Institute of Deep-sea Science and Engineering, CAS. He is a Fellow of both the Mineralogical Society of America and Geological Society of America.
Research Interests: (1) Stability of minerals as a function of pressure, temperature, and co-existing fluid compositions (including redox condition) and its applications in petrology and formation of ore deposits. (2) Physicochemical properties of geological fluids. (3) Development of quantitative Raman spectroscopic analysis technique for fluids. (4) Acquisition and evaluation of thermodynamic data of minerals and natural fluids.
Recent research includes: [a] studies of physicochemical properties of gas hydrates; [b] acquisition of thermodynamic data for metal sulfate hydrate minerals associated with acid mine drainage problems and mineralogy on Mars and Europa; [c] studies of the structures of hydrothermal fluids using the synchrotron x-ray absorption fine structure (XAFS) method for samples in diamond-anvil cells up to supercritical conditions; [d] Raman spectroscopic study of hydrocarbon-water reactions at various pressures and temperatures; and [f] redox control and measurement in high-pressure optical cells, including hydrothermal diamond-anvil cell and fused silica capillary optical cells.
