General Information
I am since January 2018 a CNRS researcher at the Fresnel Institute, Marseille, France in the team Epsilon with Boris Gralak (team leader) and Sebastien Guenneau. I was from August 2017 to December 2017 an associate research scientist and adjunct assistant professor at Columbia University. My main collaborator at Columbia University is Michael Weinstein. From August 2014 to June 2017, I was an Assistant Professor and Lecturer at the University of Utah where my main collaborators are Fernando Guevara Vasquez and Graeme Milton . I graduated (in June 2014) from Ecole Polytechnique, Palaiseau, France, where I received my PhD under the supervision of Christophe Hazard and Patrick Joly.
My research interests are in partial differential equations and numerical analysis. I focus on the propagation of electromagnetic or acoustic waves in media referred as ``complex'' for their physical properties: dispersion, diffusion, negative refractive index materials ... More precisely, it includes the following thematics:
- Mathematical study of dispersive Maxwell's equations (metamaterials, spectral theory, limiting absorption and limiting amplitude principles, resonance phenomena, cloaking, passive linear systems and theory of Herglotz functions),
- Inverse and imaging problems in electromagnetism and acoustics,
- Mathematical justification of asymptotic models for point-scatterers,
- Electromagnetic composites,
- Spectral theory in electromagnetic periodic media (honeycomb structures, Dirac points), recent topic.
My CV is available (English Version) and (French version).
