CDA (Course Development Assistant), Freshman and Sophomore Programs (FSP)Current Research and Scholarly InterestsThe most destructive tsunamis are generated by earthquakes, posing hazard to coastlines around the world. Open questions about these events are, how are they generated, what parameters will cause the most destructive waves, and how do we interpret existing seafloor data to create tsunami and earthquake early warning? To answer these questions, computer simulations (modeling) have been an effective method to study past events and assess a region's potential hazard. Many modelers use an approximate approach for modeling how earthquakes generate tsunamis, but recent events have shown assumptions in these approaches do not hold in all cases. Since these models do not fully describe the physics, they are less effective in predicting future hazards.
A more rigorous full-physics method has been developed by a previous group member that does not approximate tsunami generation, creating a more realistic model of earth/ocean interactions. This full-physics method has only been developed in 2D; however, a 3D model is needed to allow for comparison to real-world data. In collaboration with the University of Munich, I am currently incorporating the full-physics method into the open-source 3D earthquake software. This software will be the first 3D full-physics model for earthquake tsunamigenesis, providing greater insight into tsunami physics and valuable information for tsunami early warning.
In addition to my thesis work, I have focused on two other projects to study hazards. I have completed my starter project studying frictional effects on earthquake behavior and completed my second project working with the US Geological Survey on improving ground motion prediction equations used in the earthquake early warning systems. -
Aakash Ahamed
Ph.D. Student in Geophysics
BioAakash Ahamed (BS, with honors, Franklin and Marshall College; MSc, Boston College; PhD Candidate, Stanford University) is a hydrologist developing scientific methods for satellite and airborne remote sensing measurements with applications to water resources, natural hazards, and agricultural systems. As a PhD Candidate in the Department of Geophysics, his current doctoral project focuses on modeling, monitoring, and forecasting key hydrologic components of the Central Valley Aquifer System in California using techniques in data assimilation and machine learning. Aakash previously worked as a support scientist in the Hydrological Sciences Lab at NASA Goddard Space Flight Center, where he constructed satellite-based models of flood and landslide hazards. He has also developed remote sensing analyses and software at Ceres Imaging, a successful precision agriculture start up based in Silicon Valley, and interned as a GIS analyst at the World Wildlife Fund for Nature in Washington, DC.

Eliza Dawson
Ph.D. Student in Geophysics
Current Research and Scholarly InterestsI am investigating how changes in the thermal regime at the ice-bed interface could force the Antarctic ice sheet to evolve. My approach combines large scale ice sheet modeling, regional airborne ice-penetrating radar sounding analysis, and the synthesis of the two. Currently, I am using the Ice-sheet and Sea-level system model (ISSM) to learn about basal thaw processes that could drive mass loss and ultimately contribute to sea level rise.

Matthew Edward Lees
Ph.D. Student in Geophysics
BioI work on using geophysics to monitor and interpret hydrologically-induced surface deformation in and around California's Central Valley. My research focuses on improving our understanding of land subsidence induced by groundwater extraction, as well as more subtle surface deformation due to hydrologic loading. I have additional interest in sustainable groundwater management around the world, and how geophysics can be used to help tackle pressing hydrologic issues of the 21st century.
Before coming to Stanford, I studied a Masters in Earth Sciences at the University of Cambridge (2013-17) and spent time as a hydrogeologist at the International Centre for Integrated Mountain Development, ICIMOD (2017).

Karissa Pepin
Ph.D. Student in Geophysics
Current Research and Scholarly InterestsKarissa explores the use of interferometric synthetic aperture radar (InSAR), a remote sensing tool that measures mm-scale surface deformation at a resolution of 5-20 m, to study the subsurface response to fluid extraction and injection at wells, including induced seismicity, aquifer compaction, and changes in fluid flow. She also studies the InSAR signal with the goal of generating accurate time series.

Ryan Schultz
Ph.D. Student in Geophysics
Current Research and Scholarly InterestsI am interested in better understanding the geological, tectonic, and hydrological controls on induced earthquakes. Specifically, in using observational seismology techniques to infer these characteristics. In addition to this, I am also interested in describing practical regulatory frameworks to manage induced seismicity. My prior focus has emphasized earthquakes related to hydraulic fracturing, but will include other anthropogenic causes such as wastewater disposal.

Hong Yang
Ph.D. Student in Geological Sciences
Masters Student in GeophysicsBioHong 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?”.
