<p id="info"><a href="/images/portrait_large.jpg"><img src="/images/portrait.jpg" id="portrait"></a><span>I am a PhD since June 23, 2014. My thesis was prepared with the supervision of <a href="http://www.ceremade.dauphine.fr/~dolbeaul">Jean Dolbeault</a>
within the <a href="http://www.ceremade.dauphine.fr/">Ceremade</a>.
Currently, I am a postdoc in <a href="http://lmb.univ-fcomte.fr/">LMB</a> where I'm working with <a href="http://lmb.univ-fcomte.fr/spip.php?page=rubrique&id_rubrique=434">Alexei Lozinski</a> on a multi-scale finite element method for the Navier-Stokes equation.
I am also interested in analysis of non linear PDEs, of drift-diffusion type in particular, just like the Keller and Segel model for chemotaxis.
This also leads me to study some related functional inequalities.</span></p>

# Research
* Numerical analysis
* Study of two crowd motion and herding models, somewhat similar
to the Keller-Segel model.
* Numerical stability analysis for some self-similar solutions of the parabolic-parabolic Keller-Segel model.
* Asymptotic behaviour for non linear diffusion equations and related functional inequalities.
* PhD thesis : *Asymptotic study of non linear diffusion type PDEs and related functional inequalities* ([pdf](https://www.ceremade.dauphine.fr/~jankowig/These.pdf))
