Patrick Flandrin

Patrick Flandrin (; born 2 June 1955) is a French physicist, research director at CNRS researcher at , 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.
