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.

2209A Earth & Physical Sci | 530-752-1402

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.

Associate Research Scientist, retired on recall
Ph.D., University of Washington (1994)
2211 Earth & Physical Sci | 530-752-3311

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., UC Berkeley (2010)
104 Shockwave Lab | 530-754-7014
Planetary Science, Geophysics

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.

2234 Earth & Physical Sci | 530-752-1802

Igneous petrology of gabbros and basalts. Detailed petrographic, mineralogical and chemical studies to understand petrogenesis and crystallization. Current research includes gabbroic intrusions and plateau basalts of the North Atlantic province (Skaergaard intrusion, East Greenland, Iceland). Ocean gabbros and crustal formation (Indian Ocean). Ophiolites (Cyprus and Turkey). Formation of ash and slag in biomass-fueled power plants.
