Mathematical modeling

The Mathematical Modeling focus area intersects with and contributes to all other areas of research. It represents one of the key strengths of Télécom ParisTech research, which focuses on both the theoretical and practical aspects of ICST.

It can be divided into three parts:

  • Modeling content, knowledge and interactions
  • Modeling networks and systems
  • Modeling information and its ecosystems

In all these areas, advanced mathematical models are developed to effectively represent a complex reality and make the best use of it.

The two current challenges in this area are finding the right compromise between remaining faithful to reality and the effectiveness of the model (usability, computability, suitability for needs), and the ability to address problems with a high level of complexity, involving heterogeneous data, which may be massive or have gaps, involve poorly understood uncertainties or needs for explosive computing or involve complex reasoning.     

The main goal is to develop tools and methods ensuring a high level of trust and making it possible to ensure the right balance in light of two challenges:

  • Horizontal challenge: joint safety/security study: modeling and management of synergies and conflicts.
  • Vertical challenge: integration of protection/reaction mechanisms in hierarchical layers: from physical devices to applications to mathematical tools, software layers, networks and impact on society, in order to obtain an overview of a digital system’s trustworthiness.




Whether focusing on data or knowledge, mathematical modeling aims to understand and facilitate simplification, representation, visualization and mediation between people and devices. This can include the modeling of distributed systems, interactions between humans, agents and computers, probabilistic modeling, logically structured modeling of knowledge, geometric or topological modeling of complex objects etc.

Modeling is transdisciplinary as it transcends the distinctions between different fields of research. As such, at Télécom ParisTech, researchers are as likely to work on modeling communication systems, sensor networks, visual signals (image, video, 3D) or interactions between electromagnetic waves and the human body, as they are to work on modeling emotions or social phenomena.


Whether focusing on electronic circuits, optical systems, images, signals or 3D objects, or complex software, large networks, business models, human beings, concept etc. modeling can be defined as a way to reduce the complexity of the world to something that can be traced.

The use of mathematical tools makes it possible to solve a great number of application-related problems, such as information leaks in cryptographic embedded systems, Man-Computer interaction, the ways in which the human brain functions and ways to represent online communities.


Initial training

Engineering cycle

Random Modeling and Scientific Computing study track

The Random Modeling and Scientific Computing study track is based on applied mathematics, in particular in the fields of random modeling and scientific computing.


There are a wide range of applications in fields such as financial mathematics, data science, networks, signal and image processing and modeling. Program graduates find employment in technological companies or the financial industry and may choose to continue their studies by completing a PhD, whether in the form of an academic thesis or through an industrial project (CIFRE thesis).


Image study track

The Image study track includes a number of aspects of mathematical modeling, whether modeling image acquisition, the properties of these images (in terms of geometry, noise etc.), modeling image content (appearance, texture, form, scene structure) or the knowledge used to interpret images.


Image analysis methods therefore have mathematical foundations which cover a wide range of fields (probability and statistics, variational analysis and approaches, graphs and more generally discrete mathematics, algebra and topology, logic etc.) Employment opportunities are numerous, whether in industry R&D teams or in the academic world.

Master’s Degrees

Télécom ParisTech participates in four Master’s programs in the field of mathematical modeling, delivered by Université Paris-Saclay:

as well as a Master’s in Statistics and Random Models in Finance with Université Paris-Diderot.

In addition, a number of Master’s degrees in computer science and AI include courses with a strong mathematical component.

Continuing training

Télécom Évolution develops and provides innovative continuing training solutions, drawing on the educational expertise of three top engineering schools:  IMT Atlantique, Télécom ParisTech and Télécom SudParis. Our certificate programs are available through inter-company training or can be tailor-made to suit your needs. What sets our training apart is its focus on the real needs of today’s businesses. This is made possible through Télécom Évolution’s close collaboration with industry.

Télécom Evolution offers a number of training courses involving modeling skills, in particular in the field of telecommunications.

Mathematical modeling is also an intrinsic part of the Data Science and Artificial Intelligence focus area.
