Caroline Baillie is Chair of Engineering Education for the Faculty of Engineering, Computing and Mathematics at the University of Western Australia. Before coming to Perth, Caroline was Chair of Engineering Education Research and Development at Queens University, Kingston, Ontario, and she also held posts at Imperial College and the University of Sydney. Caroline is particularly interested in ways in which science and engineering can help to co create solutions for the environment as well as social problems. She founded the global Engineering and Social Justice network in 2004 and applies this lens to her own technical work on low cost natural fiber composites for developing countries. Her not-for-profit organization Waste for Life works to create poverty-reducing solutions to environmental issues. Caroline is Editor of this 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 rights and 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.
