Robert Nigbor and Graduate Student Salih Tileylioglu Study Elevator Vibration Signals
Robert Nigbor is leading a new study indicating that the subtle shaking of an elevator running up and down a building may be enough to probe that building for structural weaknesses. Nigbor and colleagues recently tested the 17-story steel-framed Doris and Louis Factor Building on the UCLA campus. |

Seawater Desalination with Advanced Membranes
Graduate student Dian Tanuwidjaja and Professor Eric M.V. Hoek are developing membrane sensors that give early warning of operational disruptions due to algae blooms at seawater desalination plants. The sensors are deployed at the Long Beach Water Department’s seawater desalination prototype facility. |

Probing the Seismic Stability of Levees
Graduate student Ted Reinert samples peaty organic soil, which underlies many levees in the Sacramento/San Joaquin Delta. Although a crucial component of California's water distribution system, levees' seismic performance remains poorly understood. The UCLA team (Brandenberg and Stewart research group) is performing large scale testing to investigate dynamic levee performance under realistic field conditions to help guide remediation efforts. |

Water Contamination from Wildfires
Ph.D. student Megan Burke collecting post-storm stream water samples from Piru Creek after the Day Fire of 2006. Megan is part of the Hydrology and Water Resources group (Prof. Hogue) studying the effects of wildfire on the chemical and physical processes of watersheds and the impact on downstream water supplies. |
