Robert Ghrist
Associate Dean, Undergrad Education; Andrea Mitchell University Professor, Mathematics & Electrical/Systems
Rob’s work focuses on those methods in applied mathematics and engineering which are global or topological in nature. Such methods have the feature of being very robust topological results are tolerant of the inherent in systems and are therefore both elegant and effective in engineering. Specific application foci include sensor and communication networks, multi-agent robotics, and dynamical systems.
