Wright earned a Ph.D. in Electrical Engineering from the University of Illinois at Urbana-Champaign with thesis work related to ink-jet printing, after which he worked ten years for Eastman Kodak on the development of toner-based printing technology. In 2007 he joined AmeriCorps VISTA and relocated to Minnesota to help the Rural Renewable Energy Alliance develop a durable and efficient solar air heat panel. In 2008 he served as a permaculturalist for the Hunt Utilities Group, which is where he first discovered and became involved with the passive building movement. Wright joined PHIUS first in 2011 as an instructor, in 2012 as a pre-certification caseworker, and in 2013 as Senior Scientist.
