About me:
Present: I am a Principal Researcher at SIFT LLC.
Past: I was an Associate Professor at
Drexel University in
Computer Science,
a Research Fellow at the
University of Edinburgh,
School of Informatics (worked on the EU
Xperience and
PACO-PLUS projects),
a Principal Research Scientist at Honeywell Labs, and in the distant past,
I was a Post Doctoral Fellow at the University of British Columbia in
Computer Science.
My Research...
focuses on integrated represenations for both probabilistic plan recognition and planning. My current work is on the relationship between formal grammars, planning, plan recognition, reasoning, learning and search. I have applied my research in a number of application areas including: computer network security, assistant systems for large scale process control, assistive technologies for elders, and most reciently, real, and virtual robots.
