About

PhD (28 years old) in physical acoustics graduated from Sorbonne University (Paris). I undergraduated in Physics and Chemistry before specializing in Physical acoustics. My PhD focused on numerical and theoretical modeling of acoustics vaporization dynamics of liquid core nanoparticles in the context of biomedical applications. This research was a cross-disciplinary subject, combining acoustics, nonlinear elasticity, phase change phenomena and, more generally nonlinear physics. Curious, autonomous and sociable, I currently hold a postdoctoral position in Physical Acoustic at the Institute of Mechanic and Engineering of Bordeaux (France).

Modeling acoustic droplet vaporization of an encapsulated droplet within hyperelastic shell or surfactants

Acoustic droplet vaporization refers to the phase change phenomena of a liquid droplet induced by an acoustic energy supply. Its modeling couple the radial dynamics of vapor bubble with the heat transfer problem. This work has exhibited important results about the vaporization dynamics and the bubble ultimate fate within its droplet. Numerical simulations has provided a threshold for complete vaporization depending on geometrical, rheological and acoustic parameters.

This work is supported by Plan Cancer 2014-2019 , project AIDA (Acoustically Induced Droplet Vaporization for Anti cancer targeted drug delivery) selected as a research project in Physics, Mathematics, and Engineering Sciences Applied to Cancer Research.
