Human Impacts

Derek Booth

Derek Booth has been at the Bren School since 2011, having worked in public agencies, academia, and the private sector as a geologist and geomorphologist. His recent projects span the fields of watershed assessment and planning, stormwater management, and stream restoration. Previously, he was a research professor in the departments of Civil & Environmental Engineering and Earth & Space Sciences at the University of Washington; he retains an active position as affiliate professor in both departments.

Ben Halpern

Ben Halpern focuses his research at the interface of marine ecology and conservation planning. His research has addressed a broad range of questions that span local to global scales, including spatial population dynamics, trophic interactions in community ecology, and the interface between ecology and human dynamics, all with the ultimate aim of informing and facilitating conservation and resource management efforts in marine systems.

I have been the Director of Ecosystem Management for UCSB's Cheadle Center for Biodiversity and Ecological Restoration (CCBER) since 2005. As the manager of the campus lagoon and other open space areas on campus, I have been active in pursuing opportunities to improve water quality and provide habitat through bioswales and treatment wetlands.

Alex Simms

My interests lie in studying how past depositional systems have responded to sea-level, climate, and tectonic changes. I use a wide variety of tools to study past depositional systems including coring, high-resolution seismic data, GPR and outcrop analysis. I am particularly interested in reconstructing Quaternary Sea Levels around the globe and the role of the Antarctic and Northern Hemisphere Ice Sheets in controlling sea-level changes over the last glacial-eustatic cycle. Although most of my work has centered around coastal systems, I do enjoy studying terrestrial systems as well.

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.

Edward Keller

Dr. Keller's research is divided into two areas: 
1) studies of Quaternary stratigraphy and tectonics as they relate to earthquake hazard, active folding and mountain building; and 
2) study of hydrologic process and wildfire in the chaparral environment in southern California.
