Birgit Lugrin (maiden name Birgit Endrass) is a
professor for media informatics at the University of Würzburg,
Germany. Since her first contact with a socially interactive agent
(the Greta agent) in 2003, she has been fascinated about the
research area. Ten years later, she received the prestigious
IFAAMAS Victor Lesser Distinguished Dissertation Award and the
research award from Augsburg University for her doctoral thesis
titled “Cultural Diversity for Virtual Characters”. Today she could
not be happier about the chance to co-edit this handbook and work
with all the great researchers who have contributed to make this
happen.
Catherine Pelachaud is Director of research at
