Cécile Bothorel received her Engineer Diploma in Computer Science in 1995, her PhD degree in Computer Science, Distributed Artificial Intelligence (Orange Labs, Rennes; CNRS/LAAS - Université Paul Sabatier, Toulouse). During her PhD, she worked on Multi-Agent Systems and Social Recommender Systems
She then worked as a researcher at Orange Labs (Lannion) for 10 years where she conducted various research in Social Media Analysis, Machine Learning and Recommender Systems. She directed phd students and postdocs, conceived and developped prototypes in the contexts of Knowledge Management, eLearning, and more generally Knowledge Sharing. She is the author of 4 patents.
In 2009, she joined the LUSSI department in IMT Atlantique, Brest (ex Telecom Bretagne). She is an Associate Professor of Computer Science, teaching Programming, Graph Theory, Social Networks Analysis, Hadoop and Big Data Analytics. She is involved in the Master of Science in Computer Science and Decision Systems (CSDS) and also in various teaching in Creativity, Innovation and Entrepreneurship (e.g. First program, Fondation Telecom).
She is in charge of the Data Science one-year specialization of the Master of Science in Engineering "Diplôme d'Ingénieur", and is especially in charge of Data Science courses and student projects.
As a member of UMR CNRS 6285 Lab-STICC, she works on Complex Networks Analysis and Graph Mining, focusing more particularly on the Detection of Communities over the social web and how to help practionners to understand and use clustering algorithms over Social Networks. The application areas are various, in Computer Science (algorithms and a toolbox to study graphs with attributes) and in pluridisciplinary fields, e.g. Management (study of the promotion process within Wikipedia administration), Economics (study of the impact of social interactions in the success of crowdfounded projects) or Ecology (study of the topology of networks of habitats of sea species and their robustness to global warming).
She has been an expert for various innovative start-ups and the evaluation of research proposals for the ANR (French National Agency for Research programs). She is a Programme Committee Member for several international and national conferences (EGC, JFGG, MARAMI, DS, BESC, ECML PKDD, WWW, ...) and reviews (IJSNM, SNAM, IJPRAI, ACM TIST, ...).

Pay2You Places (10/2011 - 04/2014)
Projet FUI12 supported by the 'pôles Finance Innovation', 'Transactions électroniques Sécurisées' et 'Images et Réseaux'.
Pay2You Places explores new payment usages via smartphones, from the payment solution to social recommendation for final users, and from an integrated payment solution to geomarketing support for professionals.
VIPEER (11/2009 - 11/2012)
Project funded by ANR Verso on Distributed Content Delivery Networks for Intra-domain Video Delivery, labelized by competitivity poles Images et Réseaux and SCS (Solutions Communicantes et Sécurisées).
The main objective of the present project is to provide methods allowing a network operator to have explicit control on traffic flows related to video distribution. VIPEER builds upon the collaboration between a traditional CDN and a peer-assisted CDN or "distributed CDN" (dCDN), i.e. an overlay controlled by the network operator using P2P paradigms. The peers in the dCDN may be network elements such as network nodes or boxes located at customers' premises.
Project supported by the 'pôle de compétitivité mondial Images et Réseaux' and the 'Direction Générale de la compétitivité, de l’industrie et des services'.
One of the biggest challenges we currently face is to keep elderly people immersed in their social environment when they leave their home and enter a retirement home. Many of them feel isolated. The TV stands as their favorite media, and our previous experiments showed that listening to vocalized local news and receiving TV messages and photos from family helped in fighting these feelings of isolation. Within this project, by using online social networks, we wish to involve the elderly in new types of interactions, more various and frequent. They will be more active and included in micro-conversations around multimedia contents. The retirement homes will benefit also from social networking capabilities. They will participate to the local news dedicated to the elderly people. In addition, the remote family will be informed of activities through an agenda and various publications.
My main research interests embrace, but are not limited to, the following topics: Complex Networks Analysis, Machine Learning and Graph Mining, focusing more particularly on graphs with attributes.
- Detection of implicit communities (clustering) in networks with attributes where both the structure of the network and the profiles of the people are combined to detect close and similar people
- Evolution of communities, dynamics of interactions
- Geolocalized social interactions to enhance remmender systems
- Datamining and network metrics to measure engagement in social media (for CRM, for eMarketing)
- Algorithms, visualization, toolbox for graphs with attributes analysis
- Application in Recommender Systems, Marketing, Management, Economics, etc.
- Data Science and Graph Theory applied to Social Networks Analysis through 3 challenges: How to sign a fulltime job contract with Google (weak ties theory), How to fill missing profil data on LinkedIn (Homophily), How to stop Zombies invasion (Epidemics).
- IA and Graph Theory in Python (PyRat): Shortest paths, Travelling Salesman Problem to win a search competition in a maze.
