About

Joshua Shaffer is a researcher whose work bridges the critical intersection of computer-aided design (CAD) and aerospace engineering. His most influential contribution, the 2005 paper "Benchmarking CAD search techniques," has garnered 49 citations and established foundational benchmark datasets for evaluating 3D shape retrieval algorithms specifically tailored to engineering problems—a vital tool for researchers developing more efficient design reuse and retrieval systems. More recently, Shaffer has focused on the practical challenges of space exploration. His 2025 paper on a "Hazard Detection LiDAR System for Robotic Lunar Landers" details the flight testing of Astrobotic’s advanced scanning LiDAR sensor at lunar analog sites. This work, though newly published, demonstrates his direct impact on enabling safe, precise landings for upcoming lunar missions. By moving from foundational benchmarking to applied sensor technology, Shaffer’s career exemplifies how rigorous algorithmic evaluation can directly support the engineering of next-generation spaceflight hardware.
