My research has focused on supporting individuals and groups in ubiquitous computing and, more specifically, on problems related to Ubiquitous User Modeling – how to track, monitor and model users (and groups) in these environments and how to provide them with continuous personalized services based on their models. In this work, I have integrated knowledge acquired as part of my Ph.D. work on Information Filtering along with the user modeling knowledge acquired both then and subsequently while working at ITC/irst (now FBK/irst), at the PEACH project, prior to arriving at Haifa.

My research aims are to suggest novel solutions for user modeling challenges in ubiquitous computing environments, by making user modeling a continuous, lifelong process, where the personal information can be made available to the environment as needed, under the control of the user.
