David had a 40-year career in the field of engineering and design of wind turbines. He began working on vertical axis wind turbines in 1981 with Indal Technologies Inc. in Ontario, Canada, and worked closely with Sandia National Laboratories on the structural dynamics of the Darrieus rotor, authoring several reports and papers on the subject. Shortly after retiring in 2015, he joined Wind Harvest as senior engineer on Model 3.0 of the company’s new cantilevered H-type turbine, bringing with him his extensive experience in critical aspects of design and engineering. He received his BSc in civil engineering from Bristol University in England, a master’s degree in structural engineering from McGill University in Montreal, and his Ph.D. in solid mechanics from the University of Calgary in Alberta. He lives in Seattle, Wash., and is an avid bike rider and skier.
