Introduction
My career goal is to understand how to develop computer systems which are useful to each and everyone! My research interests focus on three broad areas: Virtual and Augmented Reality, Visualization, and Human-Computer Interaction. Currently, I'm very interested in how interactive systems help people with disabilities to communicate and learn.

Article
The mapping of the damage caused by natural disasters is a crucial step in deciding on the actions to take at the international, national, and local levels. The large variety of representations that we have observed leads to problems of transfer and variations in analysis. In this article, we propose a representation, Regular Dot map (RD), and we c...

Unilateral Spatial Neglect is a cognitive impairment commonly observed in patients after right hemispheric lesions. A patient with this condition will show a lack of attention or response to visual stimuli presented to the left space. In order to assess visual neglect, several “paper and pencil” tests are traditionally used, like the Albert’s Test...

Cosmologists are facing the problem of the analysis of a huge quantity of data when observing the sky. The methods used in cosmology are, for the most of them, relying on astrophysical models, and thus, for the classification, they usually use a machine learning approach in two-steps, which consists in, first, extracting features, and second, using...

Virtual reality allows to create situations which can be experimented under the control of the user, without risks, in a very flexible way. This allows to develop skills and to have confidence to work in real conditions with real equipment. VR is then widely used as a training and learning tool. More recently, VR has also showed its potential in re...
