My Ph.D. research project is to analyze nonlinear dispersive equations (systems) mainly. Especially, I am interested in the Zakharov system and the nonlinear Schrödinger equations. The advisors are Tohru Ozawa (Waseda University) and Vladimir Simeonov Gueorguiev (Università di Pisa). His Ph.D. Project is under a cotutelle programme (incoming programme) with Waseda University (Japan).
