I am a computer programmer and instrumentation developer for the Sediment Laboratory at the Cascades Volcano Observatory. In the SedLab, I have three main areas of focus. First, I am re-developing the Sediment Laboratory Environmental Database System (SLEDS), the information management system used in USGS Sediment Labs to track samples and results in the lab. Second, I conduct instrumentation research and development using optical imaging to measure the particle size distribution and shape of suspended sediment. Third, I do specialty analytical projects and analytical method development for parameters such as bulk density, settling velocity, flocculation, and specific gravity. My professional goals are 1) to work on ever more challenging appliction development, web development, and database administration projects, and 2) to successfully create an instrument to measure the particle size distribution and shape of very small amounts of sediment with a known precision and accuracy.
I have an MS in Environmental Science and an MST in Science Teaching from Portland State University. My MS thesis was on sediment resuspension from urban stormwater detention ponds; my MST thesis was on how science service learning programs can promote high school girls' interest in science. Since I finished graduate school in 2008, I've been working for the CVO SedLab. Before I worked for the USGS, I was an Americorp voluteer for an environmental non-profit, a landscaper, a native plant grower, a botanical field crew leader for the Forest Service, and a technician in a plant research lab. I have a BS in Restoration Ecology from the University of California, Davis and an AAS in Computer Information Systems from Portland Community College.
