Dr. Joshua M. Pearce received his Ph.D. in Materials Engineering from the Pennsylvania State University and holds Chemistry and Physics degrees from the same institution. He then developed the first Sustainability program in the Pennsylvania State System of Higher Education as an assistant professor of Physics at Clarion University of Pennsylvania and helped develop the Applied Sustainability graduate program while at Queen's University, Canada. He currently is an Associate Professor cross-appointed in the Department of Materials Science & Engineering and in the Department of Electrical & Computer Engineering at the Michigan Technological University where he runs the Open Sustainability Technology Research Group. His research concentrates on the use of open source appropriate technology to find collaborative solutions to problems in sustainability and poverty reduction. His highly-interdisciplinary research spans areas of electronic device physics and materials engineering of solar photovoltaic cells, but also includes applied sustainability. He has more than 100 peer-reviewed publications based on his research. Most recently his group has become well-known for cutting the costs of scientific research by designing open-source hardware using 3-D printers and microcontrollers. Dr. Pearce is an energetic advocate for sustainability and open-source development in the sciences and due to his interdisciplinary background, he is uniquely positioned to provide a broad yet detailed view of this exploding area of exploration. His work in this area has been published or featured in Popular Mechanics, ArsTechnica, Nature, Chemical and Engineering News, PLOS One, and in Science: on "Building Research Equipment with Free, Open-Source Hardware". Dr. Pearce is an administrator on Appropedia, the largest online wiki dedicated to sustainability and poverty reduction (http://www.appropedia.org/User:J.M.Pearce) and a frequent contributor to Thingiverse, a repository of digital designs of real objects (http://www.thingiverse.com/jpearce).
