Aline Chevalier
Aline is interested in the impact of complexity of search problems, level of prior knowledge of individuals and aging on performance and strategies developed by users engaged in search tasks. These topics are related to the CoST project especially with WP4 in relationship with WP1. She managed previous projects (e.g., ANR PREDIT and industrial collaborations). She published more than 30 peer-review articles. More info
