Jean-Philippe Matas

Jean-Philippe Matas is a Professor at the Laboratory of Fluid Mechanics and Acoustics (LMFA - UMR 5509), affiliated with Claude Bernard Lyon 1 University (University Lyon 1). He is a key member of the EM³ team (Ecoulements Multi-physiques Multi-phasiques & Multi-échelles), focusing on complex fluid phenomena. His research spans fundamental and applied aspects of fluid mechanics with significant contributions to multiphase flow understanding.

Matas holds an HDR (Habilitation à Diriger des Recherches) obtained in 2014 and completed his doctoral thesis in 2003. His expertise has been recognized through numerous publications in high-impact journals and invitations to present at prestigious institutions like the Institut d'Alembert.

His primary research interests center on two-phase flows, with specific focus on liquid fragmentation and drop formation mechanisms, spray dynamics, air entrainment mechanisms, bubble dynamics, jet and mixing layer instabilities, vibrated granular media, and inertial migration phenomena in suspensions. His work combines experimental approaches with theoretical analysis to uncover fundamental principles governing complex fluid behaviors.

Matas's publication record demonstrates consistent contributions to fluid dynamics, with recent work (2018-2021) focusing on jet instabilities, bubble dynamics in rotational flows, and diving jet phenomena. His research shows a clear trajectory from fundamental investigations of interfacial phenomena to more complex multiphase systems with practical applications.

As an academic advisor, Matas has supervised doctoral students including Antoine Delon (thesis on liquid jet instabilities), Narendra Dev (featured in Journal of Fluid Mechanics), and Majid Rodgar (research on bubble break-up in rotational flows). His laboratory utilizes advanced experimental techniques including high-speed imaging, PIV (Particle Image Velocimetry), and other sophisticated measurement methods available at the LMFA facility.
