We are pleased to announce a *fully funded PhD position* at *Le Havre
Normandy University (France)*, within the *LITIS laboratory*, in the
RI2C research group (Interaction Networks and Collective Intelligence).
Title
-----
Analysis of the Dynamics of Interaction Networks and their Resilience
Context and Subject
-------------------
Whether they are highly publicized like social networks, essential for
the functioning of our society like transportation networks (maritime,
aerial, road, electrical), or simply ubiquitous in biological processes,
complex networks are an integral part of daily life.
Although they originate from very diverse fields, they share many common
characteristics. These networks exhibit remarkable adaptability and
robustness to disruptions. These properties emerge from the dynamic
interactions among their constituent elements. Despite these qualities,
their capacity for resilience to shocks is not without limits, and
tipping points may exist.
This project aims to study, characterize, and quantify the dynamics of
such networks and to identify tipping points that may lead to radically
different, altered structures, properties, or even systemic collapse.
The networks studied will include transportation systems (particularly
maritime networks) and biological networks, for which reliable datasets
are already available. The expected outcomes include a better
understanding of how external (exogenous) factors influence internal
(endogenous) dynamic processes governing the evolution of these systems.
Finally, this work will produce publicly available, usable datasets for
the study of dynamic networks and graphs, in various open formats.
Candidate Profile
-----------------
Education: Master's degree (or equivalent) in Computer Science, Applied
Mathematics, or related fields.
Desired skills and qualities:
(1) Graph analysis and algorithms.
(2) Data analysis.
(3) Open-mindedness towards other disciplines (biology, economics,
sociology, etc.).
(4) Algorithms and programming (experience with Java would be a plus).
(5) Good command of English (reading, writing, speaking), especially
for international collaborations.
