I am a PhD Student in Dependability and Cybersecurity for Cyber-Physical Systems at ETIS laboratory, team CELL, cofinanced by APSYS. Dependability engineer graduated from Polytech Angers
PhD in Safety and Cybersecurity of Cyber-Physical Systems
ETIS Laboratory
Since October 2020
This PhD is conducted in the team CELL of the laboratory ETIS ans is cofinanced by APSYS.
Failures of safety-critical embedded systems used in industries such as aeronautics, automotive, railway or nuclear can lead to catastrophic consequences. These complex systems, also known as Cyber-Physical Systems (CPS), also have to deal with cyber-attacks, which cause serious dysfunctions and undermine the security of such systems. The relationships between security and safety are thus at the heart of the current concerns of specialists in the field of complex embedded systems. In fact, one can no longer consider designing safe systems without ensuring they also secured. A vulnerability may compromise the functional safety of an autonomous car; on the other hand, a safety constraint such as the introduction of redundant components or diagnostic ports can increase the attack surface of such a system.
To study of the links between safety and security, our proposal builds upon the idea of extending the different mechanisms present in AltaRica, a formal language dedicated to the safety analysis of complex systems, in order to model and verify security properties. This is a "secured by design" approach, as it operates right from the design phase of the system, which, we believe, will reduce the development costs and prevent future errors.

Portfolio
Wifi module
This module was used to send the data of the shoes to a smartphone in order to process the data and store it after the run.
Prototypes
With a partner, we created a pair of connected shoes. The goal was to know which strength was applied to which part of the shoe when you are running. Then we were able to know if someone was running in a convenient of dangerous way. It required skills in Electronics, Electricity and Soldering. Also in Aduino programming and Data Processing
Interests
Climate change
Concerned about climate change
Volonteer in associations related to respect of environment and fights for climate change
Astronomy
Passionate about space discoveries and exploration.
