The Author
I have been an engineer since 2006. I earned a BS in Electrical Engineering from New Mexico State University in 2006, an MS in Optical Science from the University of Arizona in 2011, and a graduate certificate in Nanoscale Materials Science from Stanford University in 2013. I am certified as a Six Sigma Green Belt by Arizona State University. I live in Tucson, AZ with my wife Elizabeth and rescue greyhound Juliet. I enjoy cooking, e-sports, and computer programming.
