About Me

After performing a master thesis in the biomedical photonic imaging group (BMPI) of the university of Twente, I graduated from Ecole Centrale de Lyon in 2011. I then came back to the university of Twente to fulfill a PhD in the physics of fluid group under the supervision of prof. Michel Versluis in ultrasound contrast agents and graduated in 2015. I am now a postdoctoral researcher in the physics of fluids group working on ultrasound, microscale heat and mass transfer, phase change and contrast agents.

Research

My research interests include a broad array of microscale phenomena, in particular these that can lead to the generation of contrast for ultrasound and photoacoustics. Such phenomena often involve cavitation, phase change and heat and mass transfer. I also have a keen interest in therapeutic applications of microbubbles for sonoporation, sonoprinting and gene therapy. Studying microscale physics also requires a precise control of the particles properties, and in particular their size. A significant part of my research activities therefore focuses on production method and precise control of microfluidic particle and bubble production. High-speed imaging is a critical tool in such studies.

Projects

The research project in which I am involved revolve around the idea of using microscale physics in order to generate contrast or induce therapy on a single cell level. These mechanisms involve in particular phase change, microbubbles resonance and controlled production of complex particles.
