A middle-aged male, I've spent most of my life in the Pacific Northwest of the U.S., 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 and astronomy, but my professional experience has been in mechanical, optical and electrical engineering. Some of my work involved heat transport, thermal insulation, thermal inertia, refractory materials and other topics that are relevant to solar cooking. I am an experienced contributor to Wikipedia and Wikimedia Commons so I may be able to help with wiki tasks and answer questions.
