Computational Infrastructure for Geodynamics (CIG)

Dr. Dannberg’s main research topics are in computational geodynamics, in particular mantle convection and magma/mantle dynamics. Her main focus is on the development of numerical models of the Earth's interior that can help us understand how the Earth's surface has developed. In particular, Juliane is interested in the investigation of mantle plumes. Additional work includes other two-phase flow problems in magma dynamics, and grain size evolution in the Earth's mantle and its influence on rheology. Juliane is one of the maintainers of the free modeling software ASPECT (Advanced Solver for Problems in Earth's Convection) which uses modern numerical methods to support research in simulating convection in the Earth's mantle and elsewhere.

Paleoclimate and Paleoenvironmental Change

High-resolution records of climate change from ocean and lake environments as determined by palynological analyses. Reconstruction of vegetational history of late-glacial environment and its paleoclimatic implications. Evidence for the response of plant communities to climatic oscillations and analysis of environmental parameters responsible for vegetational alteration. Current research projects encompass California and the Caribbean region, including the palynological study of vegetation evolution and optimal conditions for the formation of peat in the Sacramento-San Joaquin Delta and marine sediments of the Cariaco Basin of Caribbean Sea as a source of information for paleoclimate reconstruction in a Neotropical region during late-glacial/Holocene transition.

Donna Eberhart-PhillipsDonna Eberhart-Phillips
Research Scientist
Ph.D., Stanford (1989)
2209A Earth & Physical Sci | 530-752-1402
GeophysicsStructural Geology and Tectonics

Modelling of three-dimensional seismic velocity structure and material properties; and seismotectonic analysis of active deformation. Motivated to integrate 3-D velocity and attenuation models with other geophysics and to use 3-D velocity models to understand the effects of heterogeneous material properties, to extend beyond simply interpreting crustal structure. Current research efforts have focused on New Zealand and Alaska, with emphasis on understanding subduction processes and the transition from subduction to collision. Recent work with imaging 3D attenuation structure is valuable for interpreting tectonic processes that involve fluids, and also has application to engineering response spectra.

Computational Infrastructure for Geodynamics (CIG)

As a computational geodynamicist, Dr. Gassmoeller is interested in all kinds of progress in sustainable scientific software development in geodynamics, including: 1. Investigating what influence approximations in equations have on results. Do we need to utilize upcoming larger and more heterogeneous computer architectures?; 2. Extending our modelling capabilities to systems previously thought to be too complex or expensive to investigate; 3. Maintaining community software projects that are both state of the art and easy to learn, to make geodynamic modeling a tool that is as useful and accessible as possible. This includes providing technical support to other users, helping to create a welcoming and supporting community, and spreading best practices to as many projects as possible.

Oliver KreylosOliver Kreylos
Associate Research Computer Scientist
Ph.D., UC Davis (2003)
2306 Academic Surge | 530-754-5655

Scientific visualization, computer graphics, virtual reality, human-computer interaction. Dr. Kreylos' research focuses on the development of techniques to apply virtual reality display systems and human-computer interaction devices such as the KeckCAVES to scientific research, primarily in the Earth and physical sciences. Concretely, this involves development of visualization software to create three-dimensional renderings of scientific data, development of interaction techniques to extract observations and quantitative derived data from these data, and development of support software to drive novel display and user interface hardware.

1107 Earth & Phys Sci | 530-752-5829
Igneous and Metamorphic Petrology; Geochemistry; NEAT

Experimental, igneous and volcanic petrology. Dr. Moore's research involves using high pressure and temperature apparatus to investigate the nature of volcanic eruptions and their igneous products. Phase equilibria, thermodynamics, electron microprobe analysis, and fieldwork are all part of the toolbox used to design, execute, and interpret high P-T experiments that recreate and constrain the geologic conditions and processes at depth that give rise to the volcanic rocks we observe at the surface.

John NaliboffJohn Naliboff
Assistant Project Scientist
Ph.D., University of Michigan (2009)
1227 Mathematical Sciences
Computational Infrastructure for Geodynamics (CIG)

Dr. Naliboff's research focuses on determining the relative influence of plate driving forces and lithospheric rheology on tectonic deformation patterns over a wide range of spatial and temporal scales. To investigate the origins of observed deformation patterns, he uses forward modeling of lithospheric and mantle convection processes to constrain existing or newly obtained structural and geophysical observations. Active projects include investigations of the global lithospheric stress field, outer rise deformation in the Tonga subduction system and continental extension in the North Atlantic and Gulf of California. John is also beginning projects associated with the development and testing of long-term tectonics software capable of simulating high-resolution, 3-D lithospheric deformation processes.

Paleoclimate and Paleoenvironmental Change

Paleoceanography and chemical oceanography. Dr. Russell's research focuses on development and application of geochemical tracers of changes in ocean chemistry, including metals and stable isotopes in foraminiferal shells, and redox-sensitive metals in bulk sediments. Ann uses these geochemical tracers to reconstruct changes in ocean temperature, carbon chemistry, and redox environment from deep-sea sediment cores.

Assistant Project Scientist
Ph.D., Arizona State University (2012)
3203C Earth & Physical Sci
Planetary ScienceGeochemistry

Sanborn’s research focuses on understanding the evolution of planetary objects (asteroids and small planetesimals) in the early Solar System. Understanding their evolution includes attempting to decipher melting and differentiation histories and the associated timescales. Sanborn utilizes variations in stable isotope compositions as a forensic tool to establish links between different meteorite types to place them in them in a broader context of formation on their parent asteroid or parent body. The timescales of their formation are determined using various short-lived radionuclides (⁵³Mn and  ²⁶Al) to provide million to sub-million year precision on their formation ages over 4.56 billion years ago. | Google Scholar publication

Planetary Science

Planetary formation and evolution. Dr. Spaulding conducts shock compression experiments on light gas gun platforms to investigate material properties at high pressures and temperatures. In the laboratory, Dylan investigates how materials change under extreme conditions, including the aftermath of large impact events and in the deep interiors of planets. This may include measuring equations of state, phase relations, pressure-induced chemistry and shock-induced changes in samples, all of which seek to constrain the question of how to make a habitable planet.
