Dr. Orfield is interested in product design and the role that life cycle modeling can play in the creation of products that serve rather than deplete the planet. His background in both entrepreneurship and academic research position him to understand not only the complex interaction between goods and the natural world, but also the design constraints required for commercialization. Dr. Orfield’s experience as a vocational instructor in the Republic of the Marshall Islands incited an ambition to become more active in the field of design in the developing world. His startup experiences are diverse, including founding a construction cost estimating software company, cofounding a life sciences research tool company, and cofounding a small-scale organic waste-to-energy company. Dr. Orfield’s doctoral research focused on the life cycle design of an algal biofuel that is sustainable, scalable, and salable. In the Winter of 2013 he joined the school and the Center for Sustainable Systems as a Lecturer.
