I was trained as an aerospace engineer and worked as a civilian aerospace engineer for the US Air Force for 10 years. Tiring of secure employment, I went to the auto industry where I worked as both an engineer and a lab manager before coming to Purdue in 2004. My primary fields of work were optimization, photomechanics, structural vibrations and acoustics. Now, I work mostly in structural mechanics and stringed instrument manufacturing.
