Caroline Baillie is Professor of Praxis in Engineering and Social justice at the University of San Diego, and co-founding director of the not-for-profit "Waste for Life" (wasteforlife.org) which supports vulnerable communities in the development of upcycled waste-based businesses. Baillie's research considers socio-technical processes and systems, which enhance social and environmental justice, and educational systems that promote these. She brings lessons learned from these studies and practices into the classroom of all ages, to facilitate the transformation to a more equitable and just future. Professor Baillie has published 27 scholarly books, over 200 book chapters, peer reviewed journal and conference papers, and is Editor of this book series Engineers, Technology, and Society. George D. Catalano is a Professor of Mechanical Engineering at the State University of New York at Binghamton. He holds joint appointments in the Departments of Mechanical Engineering and Bioengineering. In addition, he serves as the director of the university wide honors program at Binghamton. Dr. Catalano earned a Doctor of Philosophy and Master of Science degrees in aerospace engineering at the University of Virginia and a Bachelor of Science degree also in aerospace engineering at Louisiana State University. Prior to his present position, he has served on the faculty at the Air Force Institute of Technology, Wright State University, Louisiana State University, and the United States Military Academy at West Point. He also served as a visiting scholar at the Politechnic in Torino, Italy and at the Technical Institute in Erlangen, Germany. Dr. Catalanos research interests include turbulent fluid flows, low and high speed aerodynamics and experimental methods in physics, modeling ecosystems as well as learning strategies and paradigms, engineering ethics, engineering design and environmental ethics. He is listed in the Philosopher's Index for his published work in animal rightsand environmental ethics. Dr. Catalano has over 150 technical and educational publications and has twice been selected as a Fulbright Scholar in recognition of his work in turbulent fluid mechanics.
