Tiphaine Delaunay

Hi!

I am Tiphaine, a French post-doctorate in the field of applied mathematics.

I am currently working at LAGA on numerical reconstruction of Lamé parameters using internal observations of the displacement field in linear elasticity. This research is carried out in collaboration with Marion Darbas and Jérémy Heleine.

During my first post-doctorate, I studied mathematical modeling and data assimilation of tumor response to propranolol in angiosarcomas with Annabelle Collin, Christèle Etchegaray and François Moisan in the joint Inria-IMB project team MONC.

Previously, I did my PhD on observers for the wave equation under the supervision of Philippe Moireau and Sébastien Imperiale. For this project, I worked within the joint Inria-Ecole Polytechnique team MΞDISIM. and was funded by the ANR ODISSE.
