I am an independent contractor in instructional design & development, organizational performance improvement. Presently a doctoral candidate in instructional systems, investigating performance support systems and mobile learning applications. I'm particularly interested in energy issues: efficiency, storage, security, sustainability, etcetera. In 2009 I completed construction of a LEED-certified residence incorporating SIPS envelope, geothermal HVAC, photovoltaic array, battery bank for backup power. I tend to be an early adopter but try not to be on the bleeding edge of innovation--I've found that being too early to the party can be as painful as being too late.
