also included the topic into the curriculum of her department
and established industrial cooperations for case studies. She
held seminar series on the topic with seminars at TUM and
the Universitat Polytècnica de Catalunya (UPC) in Barcelona.
She has organized 9 international workshops and served in
different roles for international conference organization.
2) Camille Salinesi: Camille Salinesi is Professor at Uni-
versité Paris 1 where he is the head of the Centre de Recherche
en Informatique, specialized in Information Systems Engi-
neering. He published over a hundred refereed papers in
international conferences and scientific journals on various
topics such as requirements engineering, strategic alignment,
or product lines.
Dr Salinesi was involved in fundamental research projects
(FP4 NATURE, FP5 CREWS) and was the leader for collab-
orations and consultancy works for various companies such
as France Telecom, SNCF, Renault, MediaScience, and EDF).
Nowadays, he is in particular working with Renault for the
specification of the new product line of electrical and hybrid
vehicles, dealing with a number of issues such as business
alignment between sustainability goals and the product line,
and taking into account the sustainability requirements in the
design of individual vehicles.
Dr Salinesi was involved in the animation of research through
the organisation of a number of international research events.
Prof Salinesi belongs to the Program Board of the CAiSE
and to the PC of IEEE RE. Prof Salinesi was Organisation
Chair at RE’05, Program Chair of REFSQ’01, ’02, ’03 and ’14
and of CAiSE’13, General Chair of REP’99 and REP’00; he
belonged to the program board of CAiSE, and to the Program
Committee of RE, and several other events. He has also been
guest editor of the Requirements Engineering Journal and of
the Information and Software Technology Journal and was
referee in several other journals such as Telecommunication
Systems or IEEE Software.
3) Ruzanna Chitchyan: Dr. Ruzanna Chitchyan is a lec-
turer in Software Engineering at the University of Leicester,
UK. Her current researched is mainly focused on topics of
software engineering for sustainability and advanced software
modularization techniques (such as product-line based and
aspect-oriented development). Dr. Chitchyan has worked on
a number of EU and UK projects(such EPSRC projects on
Informing Energy Choices through Ubiquitous Computing and
”All-in-One” project on future sustainable infrastructures, EU
FP7 DiVA project on dynamic product lines, EU FP6 AOSD-
Europe and AMPLE projects on aspects and product lines).
She has a particular interest in effects of sustainability re-
