Oceanographer Emeritus with the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California
Ecosystem Dynamics, Project Chief: Coastal Habitats in Puget Sound - The goal of these projects is to develop scientific information and tools to support natural resource managers in the adaptive management of critical nearshore ecosystems in Puget Sound
Large-Scale Coastal Change, Project Chief: Southwest Washington Coastal Erosion Study - Research involves understanding complex relationships among sediment supply, littoral processes, and shoreline erosion or accretion in a high-energy coastal environment. Studies encompass multiple time and space scales of coastal evolution, and successfully differentiate natural and anthropogenic influences on coastal change.
Catastrophic Geologic Hazards, Co-Principal Investigator: Tsunami Hazards Study - Research effort to improve our understanding of tsunami hazards through identification and interpretation of sediments deposited from tsunamis
An International Tsunami Survey Team studying the effects of the December 26, 2004 tsunami on Indonesia“‘’’s island of Sumatra documented wave heights of 20 to 30 m (65 to 100 ft) at the island's northwest end and found evidence suggesting that wave heights may have ranged from 15 to 30 m (50 to 100 ft) along at least a 100-km (60 mi) stretch of the northwest coast.

A severely damaged home, or a portion of one, sits atop debris in Banda Aceh on the island of Sumatra. Damage was caused by a massive, highly destructive tsunami, triggered by a magnitude 9.1 earthquake just offshore of Sumatra, on December 26, 2004.
