Biography

3 minutes thesis

I have participated in the French competition Ma Thèse en 180 secondes (3 minutes thesis) which aims at promoting science through short talks of Ph.D. students. The idea is to give three minutes to explain the basics of my work without getting inside the Maths. 

My talk for the regional final is available on YouTube and deals with the problem of observation and control of traffic flows.

What are PINNs?

I participated in a Digital Futures seminar where I gave a presentation about Physics Informed Neural Networks. This is, at the moment, the most viewed video of all Digital Futures on Youtube. Here is the video.

Short biography

I am Matthieu Barreau, an Assistant Professor in the Division of Decision and Control Systems at KTH Royal Institute of Technology, Stockholm, where I have been a faculty member since September 2023. I received my Ph.D. in Control Systems from LAAS-CNRS, Toulouse, in 2019 under the supervision of Alexandre Seuret and Frédéric Gouaisbaut. My thesis was on the stability analysis of coupled ordinary differential systems with string equations. My current research interests include physics-informed machine learning, traffic flow theory, infinite-dimensional systems, and controller synthesis.

I also hold a Master’s degree in Space Engineering from KTH Royal Institute of Technology, completed in 2016, and an Engineering degree in Aeronautical Engineering from ISAE-ENSICA, Toulouse, obtained in 2016. Prior to my current position, I served as an R&D Manager at Tobii AB and as a Postdoctoral Researcher at KTH with Professor Karl Henrik Johansson.

I have been recognized for my contributions to the field, notably receiving the Best French Ph.D. thesis award from GdR MACS and Club EEA in 2020.

In 2016, I gave Maths and sciences courses at Lycée de Bort-Artense in Bort les Orgues, France for 2 months. More information about it (in French) is given in Teaching.

Teaching material

Between 2012 and 2015, I have written an introduction to Mechanics. This course has been inspired by two lessons:  "Physics 1: Classical Mechanics" given by Walter Lewin and the series of books by Richard Feymann "The Feynmann Lectures on Physics". The purpose of this new course is to address in an understandable way the key concepts of mechanics to a 14 y.o. student and trying to give him/her some physical understanding of the mathematical concepts which stay into the concept of speed and velocity for example. The writing of this course is still in progress even if it has been a long time since its last edit. The pdf version of this book is available here (in French only) and its internet version can be found on the website of OpenClassrooms (french website for e-learning).
