My research interests include robotic navigation and science autonomy (with space applications), multi-robot systems, and probabilistic planning.

• Reliable Autonomous Systems Lab - We are developing reliable, highly autonomous systems (especially mobile robots) that operate in rich, uncertain environments.

• Distributed Robot Architectures - The primary objective of this project is to develop fundamental capabilities that enable multiple, distributed, heterogeneous robots to coordinate tasks that cannot be accomplished by the robots individually.
• Federation of Intelligent Robotic Explorers Project - We are investigating and understanding fundamental issues in heterogeneous multi-robot coordination.
• Grace - The Grace project is a collaboration among several schools and research labs to design a robot capable of fully performing the AAAI Grand Challenge.
• Life in the Atacama - Robotic field investigation will bring new scientific understanding of the Atacama as a habitat for life with distinct analogies to Mars.
• Lunar Ice Discovery Initiative - Icebreaker is a proposed mission to explore the south pole of the Moon.
• Mars Autonomy - Long-distance marsrover navigation with minimal human intervention.
• Reusable Environment for Task Structured Intelligent Network Agents - An architecture for developing distributed intelligent software agents that cooperate asynchronously to perform goal-directed information retrieval and information integration in support of a varie
• Science Autonomy - The Science Autonomy project seeks to improve the accuracy and effectiveness of robotic planetary investigations by enabling automatic detection of relevant science features, classification of feature properties, and exploration planning that responds on-the-fly.
