Probalistic plan recognition and planning, reasoning based on lexicalized grammars, grounding cognition in embodied systems, human-computer interaction, and computer network security.


Dr. Geib an Associate Professor at Drexel University in the College of Computing & Informatics. Previously he was a Research Fellow at the University of Edinburgh, Department of Informatics working on the EU Xperience and PACO-PLUS projects. In the distant past, he was a Principal Research Scientist working at Honeywell Labs leading and working on DARPA programs. Before that, he was a Post Doctoral Fellow at the University of British Columbia in the Laboratory for Computational Intelligence.

Dr. Geib’s research interests focus on reasoning about and planning action under uncertainty. His current work is on probabilistic intent recognition. He is also very interested in the relationship between formal grammars, planning, plan recognition, reasoning, learning and search. He has applied his research in a number of application areas including: computer network security, assistant systems for large scale process control, and inferring the goals of elders for assistive technology systems. He is currently working on a new plan recognition and planning system based on Combinatory Categorial Grammars (CCGs).
