Staff Highlight

Peggy Johnson, USArray Data Control Analyst

As the USArray Data Control Analyst, I will be responsible for the daily monitoring and analysis of USArray data arriving at the DMC and will participate in the development and implementation of systems to improve this process.

I've been studying earthquakes for 20 years. While earning an undergraduate degree in Geology, I worked at the California Division of Mines and Geology on the 1980 Mammoth Lakes earthquake data. After graduating, I worked as a seismologist at Union Oil's Geothermal Division. Returning to school to study seismology, I earned a Master's degree in Geophysics from the University of Washington in Seattle and a Ph.D. in Geophysics from the University of California at Berkeley. Prior to joining IRIS in February 2005, I had been working at the Pacific Northwest Seismograph Network at UW as a data analyst, processing the Mount St. Helens seismic data of 2004-2005 and conducting some research on the earthquakes.

When I'm not working, I enjoy playing with my 9-year-old son, Curt. We love exploring, which often manifests itself as spontaneous road trips to the mountains or ocean. We also love hiking and camping, enjoying good company around the campfire and soaking up the moon and stars.

Tim Knight - Information Services Coordinator / Webmaster

I joined the IRIS Data Management Center in December, 2004. As Webmaster, my primary focus is on Web content, design and development projects at IRIS. I am responsible for graphic design, SAC software distribution, bulkmail requests and editing the IRIS DMS Newsletter.

Previously, I established the Multimedia Lab, a Scientific Core Resource of the Institute for Learning and Brain Sciences at the University of Washington. Prior to focusing on brain research, I worked in genetics and molecular biology at the Fred Hutchinson Cancer Research Center and The Swedish Hospital Medical Center.

As a scientist at the Hutch, I setup and managed three new shared resources: Image Analysis, Computer Graphics, and Scientific Imaging Lab. The labs provided scientists with advanced digital microscopes, imaging and graphics systems to facilitate data collection, analysis and publication. At Swedish Hospital, I photographed, counted and analyzed human chromosomes to detect genetic abnormalities, as a clinical cytogenetics technologist.

In order to share new lab techniques and data, I began developing research and educational Web sites focusing on genetics and biology, in 1994.

In my spare time, I enjoy photography, travel, hiking, reading and playing baseball with my two children, Madelaine and Henry.
