Mes travaux de recherche s'intéressent à l'étude et au contrôle des écoulements turbulents et à densité variable. Après une thèse au laboratoire IRPHE de Marseille sur le contrôle des écoulements décollés de 2008 à 2012, j'ai effectué une première expérience postdoctoral de 2013 à 2014 à l'ONERA de Chatillon sur les méthodes stabilité appliquées aux écoulements turbulents. J'ai poursuivi mon parcours par une expérience post doctoral à l'université de Caroline du Nord entre 2014 et 2018 sur l'analyse des écoulements en convection horizontale et sur la turbulence en régime stratifié.
Depuis 2018, je suis maître de conférence à l'université d'Orléans où j'interviens en tant qu'enseignant à Polytech'Orléans dans la spécialité TEAM (Technologie pour l'Energie, l'Aérospatiale, et la Motorisation). Je poursuis mes travaux de recherche au laboratoire PRISME sur le contrôle en boucle fermée d'écoulements turbulents par des méthodes issues de la théorie du contrôle et de l'apprentissage machine ainsi que l'étude de l'effet de la turbulence externe sur ces derniers.
