I am currently a Research Associate in Cardiff University. My research is supported by the EPSRC grant QUEST: Quantitative Estimates in Spectral Theory and Their Complexity (see https://cardiffquest.wordpress.com/ ).

I graduated in July 2017 from Université Paris Diderot. I worked under the supervision of Benjamin Texier on the issue of well-posedness for weakly hyperbolic or weakly elliptic systems of PDEs in Gevrey regularity ( my thesis ).

I am one of the organizer, alongside Frank Rosler and Jonathan Ben-Artzi, of the SmaSH Conference next June in Cardiff. Please find additional informations here.

I happily co-organized the conference An Analyst, a Geometer and a Probabilist walk into a bar with Jonathan Ben-Artzi in Cardiff in June 2018. It was a real success and a very joyful time!

Upcoming talks & seminars.

I have been invited to give a talk at the next Journées Jeunes EDPistes 2019 the 20-22 March in Rennes. I will be at the Conference in honor of Jean-Yves Chemin organized at the Institut Henri Poincaré the week after.
