About Me


I am currently a postdoctoral fellow at the NICHE Research Group at Dalhousie University. Previously, I was a postdoctoral fellow (2011-2013) at the BFO team, ICube Laboratory at University of Strasbourg. My PhD dissertation, defended in 2011, was on an activity recognition approach based the possibility theory and description logic. The PhD was carried out at the DOMUS Laboratory at Université de Sherbrooke.

Research Interests

My main research interests include:

  • Ambient intelligence and Context awareness
  • Knowledge representation and Semantic Web
  • Health informatics and Cognitive assistance

Currently, I am doing research on knowledge-driven activity recognition and health informatics.
