My research focuses on surface water flow generation and its interaction with the land surface at a variety of time and space scales. My work is both theoretical and applied and involves field, experimental, analytical and modelling components. The various strands of my research can be summarised as follows:

Jay Means

Over the course of his career, Jay Means has been involved in developing trace analytical methodology and its application to the analysis of environmental media including water, sediments, biological tissues, colloidal materials and air. He has published more than one hundred papers in the areas of trace analytical chemistry, environmental chemistry, and environmental toxicology of hydrophobic organic chemicals in aquatic systems ranging from the Great Lakes and major U.S. river systems to estuaries in the Chesapeake Bay, San Francisco Bay, the Gulf of Mexico, and U.S.


Welcome to the Climate Variations and Change research group. CLIVAC is headed by professor Leila Carvalho from the Department of Geography at UCSB. Leila got her BSc, MSc and PhD degrees in Meteorology at the Department of Atmospheric Sciences, University of Sao Paulo, Brazil. The behavior of our climate is governed by complex processes and interactions within the Earth's atmosphere, oceans, land, biosphere and ice. CLIVAC is dedicated to further understand the Earth's present and future climates on different temporal and spatial scales.


The NEES@UCSB facility consists of permanently-instrumented geotechnical test sites designed to improve our understanding of the effects of surface geology on strong ground motion. The instrumentation at these sites includes surface and borehole arrays of accelerometers and pore pressure transducers designed to record strong ground motions, excess pore pressure generation and liquefaction that occurs during large earthquakes. An instrumented structure is also monitored to improve our understanding of soil-foundation-structure interaction (SFSI) effects.

Andy MacDonald

Andrew MacDonald is a disease ecologist, a National Science Foundation Postdoctoral Fellow in Biology at Stanford University, and an Assistant Researcher at the Earth Research Institute. He received his PhD from the Department of Ecology, Evolution and Marine Biology at the University of California, Santa Barbara in September 2016. His dissertation focused on the effect of land use and environmental change on tick-borne disease risk in California and the northeastern US.

Duane DeVecchio

Duane DeVecchio is a broad field-based geologist with a background in structural geology and geomorphology. His research involves integrating a suite of Quaternary geochronological techniques, geologic mapping, and GIS-based topographic analysis to quantify the timing and rates of change of Earth’s surface due to depositional, denudational, and incisional processes that result from active tectonics and climate variability. DeVecchio is currently conducting research focused on the spatiotemporal tectonic and geomorphic evolution of the Western Transverse Ranges in Southern California.

Jim Boles

My research looks at the fundamental processes at the interface between dissimiliar mineral surfaces in fluids - applications to quartz-clay interaction (pressure solution) and precipitation of carbonates on mica. Clay minerals have been shown to enhance pressure solution of quartz and carbonates. Carbonate minerals and other phases have also been shown to grow selectively within biotite cleavages but not in muscovite.
