16/02/2010: We are going to organize
from 17 to 21 May 2010 a session at Wolfgang
Pauli Institute (Vienna) devoted to two-phase and compressible flows. If you would
like to participate, please, take a contact with me. This event will be
in the spirit of previous September
meeting in Vienna.
16/02/2010: During last days we
submitted a couple of new papers. The first one describes our code
VOLNA for tsunami wave modelling: "The VOLNA code
for the numerical modelling of tsunami waves: generation, propagation
and inundation". The second paper is more theoretical and deals
with application of variational principles to water wave modelling: "Practical use of
variational principles for modeling water waves".
28/09/2009: Some photos
and talks
from
our session "Numerical
methods for complex fluid flows" at Wolfgang
Pauli Institute (Vienna) are available online.
15/09/2009: From 21 to 25 September
2009 we organize a session at Wolfgang
Pauli Institute (Vienna) entitled "Numerical
methods for complex fluid flows".
30/03/2009: Magazine "La Recherche"
(N429, April 2009) published an article about our recent results on
mathematical modelling of powder snow avalanches. The preprint of
our work can be found here.
18/02/2009: My
interview on general strike of universities in France was
published in a russion journal Gaudeamus
based at Saint-Petersburg. It is in russian, of course...
19/01/2009: Finally
we finished and submitted our first article on powder-snow avalanches
entitled "Numerical
simulation of powder-snow avalanche interaction with an obstacle"
to Applied
Mathematical Modelling
01/12/2008: I
am going to deliver a talk on numerical modelling of tsunami waves at
the workshop "Oceanography
and mathematics", Ecole Normale Supérieure de
Paris, 26 - 28 January 2009
22/10/2008: Our
paper "Energy
of tsunami waves generated by bottom motion" was accepted to
Proceedings of the Royal Society A.

TEACHING
I give essentially practical classes (Travaux Dirigés) for
third-year
students at the
Department
of
Mathematics,
ENS
Cachan. These students prepare
agrégation
(civil service competitive examination for some positions in the public
education system). The lectures are given by
Frédéric Pascal,
Jean-Michel
Ghidaglia and
Frédéric
Dias.
Students use MatLab as programming language for numerical solution of
formulated in exercises problems.
I have been assisting in teaching the following subjects:
- Scientific computing (calcul scientific)
- Numerical methods of Linear Algebra
- Numerical methods for PDE
- Numerical methods of Optimization
- a few practical classes on Differential Geometry with Maple
(for students in Licence level)
- a few classes on Spectral Methods for MN2MC
students
