Reference excerpt

Patrick Flandrin (French pronunciation: [patʁik flɑ̃dʁɛ̃]; born 2 June 1955) is a French physicist, research director at CNRS researcher at École Normale Supérieure de Lyon, and member of the French Academy of Sciences.

Biography After receiving the engineer degree from ICPI Lyon (now CPE Lyon) in 1978, Patrick Flandrin obtained the Doctor-Engineer degree in 1982 and "Doctorat d’État ès sciences physiques" in 1987, both from the Institut National Polytechnique de Grenoble. He joined the Centre National de la Recherche Scientifique (CNRS) in 1982, where he holds now a senior researcher position ("exceptional class research director"). Affiliated with ICPI Lyon from 1982 to 1990—where he has been Head of the Signal Processing Laboratory from 1987 to 1990—, he moved in 1991 to the École normale supérieure de Lyon, where he created a "Signals, Systems, and Physics" group within the Physics laboratory. Among various responsibilities at the national level, he has been Director of the CNRS cooperative structure "GdR ISIS" from 2002 to 2005, and President of GRETSI (the French association for signal and image processing) from 2009 to 2019. Elected to the French Academy of Sciences in 2010, he served as its vice president in 2019–2020 and President in 2021–2022.

Scientific contributions Patrick Flandrin is a specialist of signal processing. Since his PhD in 1982, he has conducted research activities in three main directions. He first contributed to fundamental advances in time-frequency analysis, with the development of comprehensive approaches aimed at analyzing, decomposing, and processing nonstationary signals. He also took an active part in the development of wavelet theory since its very beginning, with highly cited seminal contributions to the multiresolution analysis of scaling processes that paved the way to numerous applications in domains as diverse as biomedical engineering or internet traffic modeling. More recently, while revisiting a number of fundamental issues in nonstationary time series analysis by new, data-driven approaches, he moved to the study of specific complex systems involving human activities, with a shift towards network-based approaches.

Worked examples

Example 1 — a first encounter with Patrick Flandrin

Start with the simplest possible case. Write down what Patrick Flandrin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Patrick Flandrin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Patrick Flandrin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Patrick Flandrin

In research: Patrick Flandrin appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Patrick Flandrin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Patrick Flandrin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, French National Centre for Scientific Research awards, French physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Patrick Flandrin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
