Brad Clement is a senior member of the Artificial Intelligence Group at the Jet Propulsion Laboratory in Pasadena, CA, where he is developing methods for coordinating planning and scheduling for single and multiple spacecraft/missions.

Brad Clement received a bachelor degree in computer engineering from the Georgia Institute of Technology and M.S. and Ph.D. degrees in computer science and engineering from the University of Michigan, Ann Arbor, where he was a member of the Distributed Intelligent Agents Group. Before graduate school he worked as a software research engineer for Matsushita Electric Works (National/Panasonic) for two years in Osaka, Japan.

Research Statement

My research is centered on developing techniques and software that leverage models of human domain knowledge to coordinate collaborating or competing agents (software, robotic, or human) in performing real-time planning, scheduling, and execution tasks in an uncertain or partially known environment. My interests include artificial intelligence, multiagent coordination, robotics, abstraction, planning, scheduling, execution, distributed systems, real-time systems, integrated AI, control architectures, AI in games, …

I am currently leading the development of planning model capture and validation software for the ETDD Autonomous Systems and Avionics Foundational Domain. I am also exploring the parallelization of ASPEN for multicore processing. The selected publications below describe this and other work.
