A retired male, I've spent most of my life in the Pacific Northwest, but have lived briefly in Texas, New Mexico and Hawaii. My interests are the natural and physical sciences, the Washington region, and occasionally current events. My education is in physics (BS) and astronomy (MS), but my professional experience has been in mechanical, optical and electrical engineering. I started editing in 2005 and have more than 10,000 edits on Wikipedia. I have added more than 6600 images to Wikimedia Commons including photographs of almost 700 species of biota.
