At the annual awards ceremony at USGS in Menlo Park on March 3, Brad Ito was presented with the Superior Service Award of the Department of the Interior in recognition of his exceptional contributions to ensuring the success of the ion microprobe laboratory. In the eleven years since the SHRIMP-RG was installed, Brad has become widely known for his technical innovations, trouble-shooting prowess, and dedication to keeping this complex instrument fully operational twenty-four hours a day, seven days a week. Brad has unselfishly committed long hours, often on short notice on weekends and into the night, to ensure that the ion probe is in optimum operating condition. For the countless SHRIMP sessions that he has enabled or salvaged, there are dozens of grateful scientists, many of whom traveled large distances for time on the instrument booked months in advance. The award was presented to Brad by Anne Kinsinger, Regional Director, on behalf of Marcia McNutt, USGS Director.
The SHRIMP Lab welcomes Dr. Jorge Vazquez as the U.S. Geological Survey's staff scientist for the Stanford–USGS Ion Microprobe Laboratory. Dr. Vazquez was selected as a result of a national search for a research geologist to work with other Survey scientists in the laboratory and to develop new USGS research projects with the SHRIMP-RG.
Dr. Vazquez received his Bachelor's degree from California State University, Los Angeles, M.S. from Northern Arizona University, and Ph.D. from UCLA. Jorge studied pyroclastic-surge deposits and geology of the Hopi Buttes volcanic field, Arizona, for his Masters thesis. At UCLA, he focused on ion microprobe U–Th–Pb geochronology of allanite and zircon in Quaternary rhyolites (Toba Tuff, Indonesia; postcaldera rhyolites, Yellowstone) and on uranium-series geochemistry. His bibliography also includes papers on petrology and accessory mineral geochronology of young rhyolites from the Coso volcanic field and Salton Buttes, California, and plutonic rock fragments (xenoliths) from Hualalai and Mauna Kea volcanoes, Hawaii. Since 2004, Jorge has been Assistant Professor of Geology at California State University, Northridge. He brings a strong background in ion microprobe geochronology, igneous petrology, geochemistry, and volcanology to the SHRIMP lab. We look forward to his joining the SHRIMP lab team and to his involvement in research with Survey colleagues nationally.
Joe Wooden retires from the USGS and begins a new era as a senior research associate within Stanford University's Department of Geological and Environmental Sciences (GES).
With Joe's retirement from USGS, Charlie Bacon is now Co-Director for USGS at SUMAC.
