Education PhD in
Cognitive Science. Master of
Artificial Intelligence and Algorithmic (specialisation: Image processing). Engineer
in Computer Science (Specialisation: Computer systems). Research My
research focuses on the understanding of human-human social interaction for
the development of an automatic and multimodal affective human-machine
interaction system, similar to everyday life human-human social communication.
My main research
includes computer vision, machine learning and visual perception applied to
human-machine interaction. I am
particularly motivated by medical-context applications such as pain
monitoring and the development of pain assessment tools for
individuals who are not able to communicate pain verbally. My current work
includes dynamic recognition of facial expressions in video sequences, pain
and depressed behavior assessment and human-human social behavior applied to
human-machine interaction. News The FG
2011 Facial Expression Recognition and Analysis Challenge (FERA2011) Current Project Automatic
Analysis and Recognition of Depressive Behavior: The aim of
the project is the use of the Automated Facial Image Analysis (AFA) developed
at the CMU/Pitt as reliable, valid, and efficient measurement of emotion
expression and related nonverbal behavior for assessment of symptom severity
in depression. AFA is capable of extracting both the type and timing of
nonverbal indicators of depression. Such automatic system could improve
clinical assessment of symptom severity and evaluation of treatment outcomes
when combined with information from interviews and self-report questionnaires. Joint
work with Jeff Cohn, Takeo Kanade, Simon Lucey, Fernando De la Torre, and Zara Ambadar. Previous Link Publications PhD Thesis in
