About

Ramayya Krishnan is a pioneering researcher whose work spans the critical intersection of information systems, computational social science, and advanced manufacturing. He is perhaps best known for his influential research on shopbots—shopping robots that automate consumer price comparisons across vendors. In his highly cited 2004 paper, "Designing a Better Shopbot," Krishnan explored how to optimize these digital tools for consumer welfare, a contribution that has garnered over 130 citations and laid foundational insights for e-commerce and online market design. Beyond digital marketplaces, Krishnan has made significant strides in manufacturing innovation. His 2002 work on robot-assisted shape deposition manufacturing, with over 60 citations, advanced the field of solid freeform fabrication by demonstrating how robotic systems can directly deposit and fuse metal layers to create prototype shapes. This research bridges robotics and materials science, offering practical pathways for rapid prototyping. As a professor and former Dean at Carnegie Mellon University, Krishnan’s interdisciplinary impact is profound—his work not only shapes how we shop online but also how we build physical objects, making him a key figure in both information technology and manufacturing engineering.
