Dr. Hod Lipson is an associate professor of mechanical and aerospace engineering and of computing and information science at Cornell University, where he also directs the Creative Machines Lab, which focuses on novel methods of automatic design, fabrication, and adaptation of virtual and physical machines. In addition, he has led work in evolutionary robotics, multimaterial functional rapid prototyping, machine self-replication, and programmable self-assembly. In his current research he focuses on what he considers two grand challenges of engineering: (1) Can we design machines that can design other machines? (2) Can we make machines that can make other machines? Both questions lie at the crux of understanding the engineering process itself, and progress on these fronts can offer huge leverage in the ability to design, make, and maintain increasingly complex systems. Biological life has answered these challenges in ways that dwarf the best teams of human engineers; therefore, he uses primarily biologically inspired approaches, as they bring new ideas to engineering and engineering insights into biology. Dr. Lipson is coauthor of the forthcoming book, Fabricated: The Promise and Peril of a Machine That Can Make Anything. He received a PhD from the Technion – Israel Institute of Technology in 1998 and did postdoctoral work at Brandeis University and the Massachusetts Institute of Technology.
