    Hong Yang

    Ph.D. Student in Geological Sciences
    Masters Student in Geophysics

    BioHong Yang is currently a PhD student in Geological Science working with Wendy L. Mao. He joined Mao’s lab at Stanford University in 2018, after finishing his Master’s Degree at HPSTAR, Shanghai, where he was supervised by Jung-Fu Lin. His Master’s thesis focused on the experimental determination of iron isotopic fractionation behavior of lower mantle phases using the Synchrotron X-ray technique NRIXS. Before that, he was an undergraduate majoring in Geochemistry at the University of Science and Technology of China. There he performed the quality assessment of bottled drinking water and water from Lake Chao under Fang Huang’s supervision.

    Hong’s research interests include the chemical (especially isotopic) evolution of the Earth and other planetary bodies; structure and sound velocities of iron-alloys at high pressure; pressure-induced electronic, magnetic, elastic and structural transitions in materials; as well as high pressure photon science. His recent research was published on Earth Planet. Sci. Lett. 506, 113-122 (2019), entitled “Iron isotopic fractionation in mineral phases from Earth’s lower mantle: Did terrestrial magma ocean crystallization fractionate iron isotopes?”.

    David Zhen Yin

    Research Scientist

    BioDavid Zhen Yin is the Research Scientist at Stanford Center for Earth Resources Forecasting. He develops data scientific approaches for prediction, uncertainty quantification and decision making in earth resources exploration and developments (including critical minerals, groundwater, and oil and gas).

    David developed broad experiences in working with complex projects involving the academia and industry as well as broad knowledge about the fields. His research delivered several key technologies that have been transferred as in-house technologies in Chevron, Equinor, and KoBold. His research developments have been implemented to a broad spectrum of subjects, from Antarctica bed topography modeling, to critical mineral explorations in Canada/China/US, to North Sea and Gulf of Mexico projects.

    Prior to joining Stanford, David was a Research Associate (Reservoir Geophysics) at Edinburgh Time-Lapse Project at Heriot-Watt University in Scotland, leading a research project in collaboration with Equinor from 2016 to 2018. He was also a Technology Consultant at Equinor's Research Center in Bergen, Norway. He was then a Chevron CoRE Postdoctoral Fellow at Stanford from 2018 to 2021.

    David received his PhD in Geosciences from Heriot-Watt University, UK, in 2016, and B.Eng from China University of Petroleum in 2011. His research interests include data science for geosciences, geological uncertainty quantification, and decision making under uncertainty. He has authored tens of articles in peer-reviewed journals and international conferences on these topics.
