Assistant Professor

About Me

Since April 2023, I work as an assistant professor—with a research focus on Aeroacoustics—in the Engineering Fluid Dynamics (EFD) group. 

At the Eindhoven University of Technology, I earned an Applied Physics MSc degree with the specialization “physics of transport in fluids.” In addition, I obtained a PhD degree in Fluid Mechanics from CentraleSupélec (Université Paris-Scalay). To obtain this degree, I investigated self-sustained pressure pulsations in solid rocket motors. This PhD research project was a collaboration between: ArianeGroup, CentraleSupélec and the von Kármán Institute for Fluid Dynamics (VKI). From May 2019 to April 2021, I was a DLR-DAAD Postdoctoral Fellow at the German Aerospace Center (DLR) in Berlin-Charlottenburg. During my stay at the DLR, I focused on advancing the fundamental understanding of what is referred to as indirect combustion noise in the jargon. Starting in May of 2021 until March 2023, I worked at Imperial College London—where I investigated aeroacoustic properties of a single perforation in a finite-thickness plate.
