Clément Moreau

Postdoctoral Researcher in Applied Mathematics

I am a JSPS postdoctoral fellow at RIMS in Kyoto University since October 2020. I am working there with Dr. Kenta Ishimoto.

I have obtained my PhD in June 2020. It took place both at Inria Sophia-Antipolis and Université Paris Dauphine-PSL, under the supervision of Laetitia Giraldi, Pierre Lissy and Jean-Baptiste Pomet.
During year 2016-2017, I was invited at University of York by Dr Hermes Gadêlha, who is now Senior Lecturer at University of Bristol (UK).
I am a former student at Ecole Normale Supérieure de Cachan (France).

Here is my CV.

Research Interests

My research deals with mathematical control theory and its applications to microfluidics and micro-swimming.

Micro-Swimming

I study the motion of swimming micro-organisms through modelling, controllability analysis and numerical simulations. I use the tools of control theory on various models to better understand, predict or influence related phenomena.

Magnetic micro-robots and local controllability

I have worked on a model of magnetized elastic micro-swimmer, controlled by an external magnetic field, and studied its controllability properties around equilibria. In a more general framework, I am interested in local controllability conditions for control-affine systems.

State-constrained controllability

I take interest in the subject of state-constrained controllability of PDE systems. In particular, I am investigating nonnegative state controllability of linear and semilinear coupled parabolic systems.
