Richard Cowen

Senior Lecturer Emeritus
University of California Academic Senate Distinguished Teaching Award recipient, 1993
Ph.D., Cambridge (1966)

Functional and anatomical reconstruction of fossil invertebrates; the interrelationship between geology and people. Projects include work on trilobite eyes, algal symbiosis in fossils, and analysis of the human impact of a historic earthquake in the area. See also CV, books, publications, and courses.

John Dewey

Distinguished Professor Emeritus
Ph.D., University of London (1960)

Basic interests and knowledge are in structural geology and tectonics from the small-scale materials science of deformed rocks to the large-scale origin of topography and structures. Ongoing field-based research is on the rock fabrics and structures of transpression and transtension especially in California, New Zealand, Norway, Ireland and Newfoundland. Evolving interests are in the neotectonics of California and Nevada in the relationship among faulting,topography, and sediment provenance, yield and distribution. Derivative interests are in the geohazard of volcanoes, earthquakes and landslides.

Charles G. Higgins

Professor Emeritus
Ph.D., UC Berkeley (1950)

Geomorphology; environment and morphology of beaches and coasts; landscape and drainage development by groundwater sapping and subsurface alteration.

Eldridge M. Moores

Distinguished Professor Emeritus
2013 Distinguished emeritus award
Ph.D., Princeton (1963)

Interests lie in tectonics, structural geology, and petrology;  ophiolites and their significance, the tectonics of Alpine-type mountain belts, Cordilleran tectonics, Precambrian tectonics, and K-12 education and public awareness of Earth Science. His field experience has included work and/or field excursions in about 60 countries including all seven continents.  Moores is relatively fluent, if rusty, in Modern Greek, German, and French, and can survive in Italian and Spanish.  Moores is the author or co-author of over 130 publications, including two textbooks (with R. J. Twiss), entitled Tectonics, and Structural Geology (2nd Ed),  monographs, and books for a popular audience.  He is prominently featured in John McPhee's books Assembling California and Annals of the Former World.   Moores was Editor of Geology from 1981-87, and Science Editor of GSA Today from 1991-95. Moores was 1996 President of the Geological Society of America and 2004-2008, Vice President of the International Union of Geological Sciences.

Jeffrey F. Mount

Professor Emeritus
UC Davis Distinguished Public Service Award, 2005
Ph.D., UC Santa Cruz (1980) 

Fluvial geomorphology, ecogeomorphology, river and water resource analysis. Research emphasis on the geomorphology and ecology of rivers and streams, their response to changes in land use/land cover and flow regulation, and their restoration and assessment. Projects include restoration of river floodplains, management of levee systems in floodplain/estuary systems, re-operation of hydropower systems to improve aquatic ecosystems and adapt to climate change, and restoration of spring fed streams and meadow systems. Outreach includes assisting agencies and non-profits in assessment and formulation of river management policies.

James R. Rustad

Professor Emeritus
UC Davis Chancellor's Fellow, 2005-2006
Ph.D., Minnesota (1992) 

Interfacial and mineral surface geochemistry; mineralogy; mineral physics. Research is focused on computational chemical models of interfacial structure as well as surface charging, sorption, dissolution, and precipitation phenomena at oxide-water interfaces. Computational methods are also applied to problems in mineralogy and in aqueous and silicate melt geochemistry, including physics of hydrated minerals, ligand exchange and electron transfer reactions.

Professor Emeritus and Research Geologist Emeritus
Ph.D., Stanford (1978)

Petrology and mineralogy of active and fossil hydrothermal systems in terrestrial and submarine settings: high temperature alteration of basaltic deposits related to the Icelandic Deep Drilling Project, Reykjanes and Krafla geothermal systems;  fluid-rock interaction in active geothermal systems in California.

Donald L. Turcotte

Distinguished Professor Emeritus
Ph.D., Caltech (1958)

Application of dynamical systems to geological problems, including crustal deformation, seismicity, topography, forest fires. Geodynamics, including mantle convection and the forces that drive the plates and result in seismicity, volcanism, and mountain building at the earth's surface. Planetary geology and geophysics, especially the interpretation of data returned from various planetary missions.

Robert J. Twiss

Professor Emeritus
Ph.D., Princeton (1971)

General research interests include the mechanisms and mechanics of rock deformation and the interpretation of associated structures. Earlier research interests include paleopiezometry, which is the use of the microstructures of ductilely deformed mineral grains to infer the paleostresses associated with deformation; and the systematics of fold geometry. Twiss co-authored the textbooks Structural Geology, 2nd Edition (Twiss and Moores, W.H. Freeman & Co., 2007) and Tectonics (Moores and Twiss; W.H. Freeman & Co., 1995).
