Ph.D. Student in Geological Sciences
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?”.

Postdoctoral Research Fellow, Earth System Science
BioI am an ecosystem ecologist using data-driven approaches to study global environmental changes, including climate change, land use land cover change, and coupled natural and human (CNH) systems. My data comes from both remote sensing observation and field measurements. My current project is studying methane emissions from abandoned oil and gas wells and from home appliances in California.
Educational Affairs Program Director, School of Earth, Energy and Environmental Sciences
BioAs the Educational Affairs Program Director and a Lecturer in the School of Earth, Energy & Environmental Sciences, Audrey develops educational programs and courses that connect academic learning with real world applications. In this role, Audrey serves undergraduates, graduate students, and postdoctoral scholars in Stanford Earth.
She is an instructor in the Earth 1 Know Your Planet series of courses designed to introduce students to the breadth of the Earth sciences. Additionally, Audrey oversees the School's undergraduate peer advisors, who advocate for student needs within the School as well as create educational programs and social events for the undergraduate community at large.
In her role, Audrey has developed a series of Earth courses that support graduate students and postdocs in developing powerful portfolios that include academic excellence, professional skills, and personal development. In addition, she oversees the School's graduate student TA mentors, who serve as resources across the School in teaching assistance.
Audrey also hosts a series of co-curricular educational programs that allow undergraduates, graduate students, and postdocs the chance to gain practical experiences and knowledge. These include a peer-taught Skillshare series, a faculty-led Pro-Seminar series, and a variety of workshops throughout the year.

David Zhen Yin
Postdoctoral Research Fellow, Geological Sciences
BioDavid Zhen Yin is the Postdoctoral Researcher working on Stanford-Chevron CoRE Project at SCERF (Stanford Center for Earth Resources Forecasting). He develops Bayesian Evidential Learning for predictions and uncertainty quantification of oil/gas reservoirs.
Prior to joining SCERF, David was a Research Associate at Edinburgh Time-Lapse Project at Heriot-Watt Institute of Petroleum Engineering in Scotland, leading a research project in collaboration with Statoil from 2016 to 2018. He developed the “WELL2SEIS” technique that efficiently integrate 4D seismic with reservoir engineering data to improve reservoir models. This technique has been applied to seven North Sea projects, and has become Statoil’s standard in-house technology. During this period, he was also a Reservoir Technology Consultant at Statoil Research Center in Bergen, Norway. David developed broad experience in working with complex projects involving the industry as well as broad knowledge about the fields.
David obtained his PhD in Reservoir Geophysics from Heriot-Watt University, UK, in 2016, and B.Eng (Petroleum Engineering) from China University of Petroleum in 2011. His research interests include Bayesian Evidential Learning, reservoir modelling and updating, uncertainty quantification, time-lapse reservoir monitoring. David has authored more than 10 publications in peer-reviewed journals and international conferences. He was awarded the SEG Frans and Alice Hammons Award in 2014.
Ph.D. Student in Environment and Resources
Student Employee, Center for Teaching and Learning
Current Research and Scholarly InterestsLeehi studies greenhouse gas inventories and how countries use (or misuse) scientific knowledge in developing national carbon inventories and climate policies. She is particularly interested in the global carbon cycle, and how ecosystem and forest carbon is understood by policymakers.
Hannah Elizabeth Tracy Young
Undergraduate, Earth Systems Program
BioHannah is an undergraduate in the Earth Systems Program with a focus on Land Systems and is primarily interested in land use and the methods used to monitor land use change. She is a student advisor for the Earth Systems program as well as a docent at Jasper Ridge Biological Preserve. Hannah is originally from Spearfish, South Dakota located in the beautiful Black Hills where she gained a love for the environment at an early age. Her passion has continued to grow throughout her time at Stanford with engaging courses on campus, studying abroad in Australia, and working as the naturalist at Stanford Sierra Camp. Outside of her academics, she can be found hiking, mountain biking, climbing, doing crosswords, or enjoying a nice cup of coffee.
