International partnership Georgia Tech – CNRS
Established in 2006, the International Research Lab (formerly International Mixed Unit – UMI) is managed by both Georgia Tech in Atlanta through the “Mirror Lab” and the CNRS in France. Researchers, postdocs, students, and established academic and industrial partners joining forces for research around four main themes:
- Smart Materials (functional and structural)
- Non-destructive evaluation by acoustic and THz spectroscopies
- Robotics and Artificial Intelligence
- Simulation and evaluation of complex systems
Over the past five years, 65 doctoral students from all around the world were supervised by IRL researchers. Many were enrolled at Georgia Tech, while others were enrolled at partner institutions, such as the University of Lorraine, CentraleSupélec, and ENSAM. Most of these doctoral students have gone onto careers with large industrial groups.
Every four years, the partnership between Georgia Tech and CNRS is renewed. In the 2018 renewal, Jean-Paul Salvestrini was named director of the GT – CNRS 2958 lab.

By Alexandra N. Ramotar
Alexandra Ramotar (GTAE) placed second at the AIAA 2023 Region II Student Conference for her presentation title “An Implementation of the A* Search Algorithm for Dynamic Message Routing in Homogeneous Communication Satellite Networks”. She adapted, tested, and analyzed an algorithm for the challenging problem of routing a message along a network of nodes which are not fixed in space, nor in relation to one another. Further, she demonstrated its effectiveness relative to a best-first algorithm through quantitative and qualitative assessments.
Alexandra supported ongoing research at Georgia Tech Europe through her work, providing valuable insights on existing efforts while laying the foundation for further developments and explorations.
Center for Materials Innovation
STRATEGY – Our objective is to understand the relationship between processing, microstructure and properties of materials. To this aim, we develop simulation models of diverse physical processes of microstructure evolution in metals at different time and length scales and utilize modern methods of materials informatics. In particular, the Process-Structure-Property (PSP) linkage will form the intellectual basis for integrating data science techniques into a more coherent understanding of materials science and engineering.

Data-driven Robotics for Environment Assessment and Monitoring – DREAMLAB
STRATEGY – Development of automated systems to monitor environments over long periods of time. Automation may be expressed in a large spectrum going from automated processing of a large dataset to autonomous operation of a mobile robot.
Focus on outdoor environment from natural ecosystems (lake/forests) to industrial, for monitoring and inspection needs.

Nonlinear Dynamics in Photonics and Electronics
Terahertz Imaging & Spectroscopy
STRATEGY – Nonlinear dynamical systems underly a plethora of physical, biological, and social phenomena. They are useful in building systems that provide superior performance compared to purely linear systems. We develop photonic and electronic applications that take advantage of the properties of nonlinear dynamical systems.
STRATEGY – THz imaging is a new modality for the 3D inspection of numerous electrically insulating materials, including the interior of optically opaque objects. It is nondestructive, contactless and non-ionizing. We use THz imaging and spectroscopy to investigate the dielectric properties, structure, response to stress and defects in materials. THz imaging can provide new or additional information with respect to other nondestructive-evaluation techniques.
