Graduated and received Ph.D. degree at Ecole Nationale des Ponts & Chaussées
Ecole Nationale des Ponts & Chaussées (ENPC) is a leading and prestigious Engineering University in
France, "Grandes Ecoles". Students enroll this university after succeeding a nationwide competitive
examination at advanced mathematics, physics and chemistry. CERMICS is one of its laboratories
specialized in applied mathematics and computer sciences.
Work and Research experience
June 2004 -> today: Quant at IXIS CIB / Equity Derivatives and Arbitrage
Project: Development of pricing libraries for exotic options.
Key words: Models: Black and Scholes, local volatility, stochastic volatility, market
density, copulas. Products: vanilla options, barrier options, cliquets, equity
default swaps,...
Dec. 2003 - May 2004: Consultant at MathFi Project in INRIA (The French National Institute for Research
in Computer Science and Control).
Project: Calibration of stochastic volatility models with jumps (Heston and Merton
models). My role is to develop the pricing routines using both closed forms and
PDE methods (for Heston model) in the Premia pricer. Next I use the BFGS
method for developping robust calibration strategy.
Key words: Stochastic volatility, smile, jump process, calibration, optimization.
Dec. 2002 - Oct. 2003: Post-Doc at Cermics, Ecole Nationale des Ponts & Chaussées. Application of
optimization algorithms to problems from quantum physics and development in the
"C++ OptimLib".
June - July 2003: Invited research at the Computational Chemistry and Photonics department of
Sherbrooke University (Canada).
Project: Development of optimization tools for ultra-short laser generation.
April-June 1999: Research student at INRIA.
Project: Study of wave scattering by a moving object. My role was to adapt and to
implement the fictitious domain method in the case of a moving object.
Aug. 1997 - Aug. 1998: Research student at DER (Research center) of Electricité de France (French
electricity supplier provider).
Project: Introduction of a new finite element in the Finite Element Code Code_Aster
developed by EDF. After a bibliographic study, I implemented one model of an
enriched one-dimensional finite element and next I integrated this element into the
Code_Aster.
April - July 1996: Research student at the Politecnico Di Torino (Italy).
Project: Resistance to the shearing of discontinuous rock structure under static and dynamic
loadings. By an experimental approach, I studied different models of the rock
structures behaviors.

Ph.D. thesis
1999 - 2002: Ph.D. student in Applied Mathematics. Cermics, Ecole Nationale des Ponts &
Chaussées.
Subject: Numerical Optimization and Optimal Control: (applications for quantum physics).
Supervisor: Pr. Claude LE BRIS.
To achieve the objective set in the study, advanced mathematical and numerical techniques including automatic
differention, optimal control were implemented through evolutionary and hybrid algorithms.
The most important part of this work concerns the application of control and optimization tools to the laser control
of molecular systems. The main part of this thesis (Chapters 1 to 6) is devoted to laser control of molecular
orientation. Our goal is to find the laser field which orients the molecule along its direction.
In the first chapter we present the orientation problem and the different optimization methods we have developed.
In the following chapters we give more details about the optimization methods we used (Chapters 2 and 3) and the
main results obtained (Chapters 4, 5 and 6).
In Chapter 7 we present another laser control problem using the same optimization tools. In this problem we study
the optimization of the High Harmonic Generation (HHG) of an hydrogen atom excited by a laser field. The goal is
to create an ultra-short laser field (attosecond laser).
In Chapter 8 we present some numerical tools developed for a geometry optimization problem in molecular
chemistry. In this chapter we optimize the position of N particles where the interaction is given (among other cases)
by the Lennard-Jones potential.
Finally, in Chapter 9 we give some theoretical results about the Optimized Effective Potential (OEP) problem for
the Hartree-Fock energy minimization. In this problem we ask about the validity of the simplification consisting in
replacing the Hartree-Fock equations by some eigenvalues equations of a simplified form.
