Experience

Research Engineer

CNRS

Jan 2022 – Present Orsay

Part of Systems team at IDRIS. Main activities include designing and implementing various solutions on the Jean Zay platform

Research Engineer

INRIA

Jan 2021 – Dec 2021 Lyon

Part of Square Kilometer Array (SKA) telescope project. Main activities include benchmarking the HPC codes that will be depolyed on the Science Data Processor (SDP) of SKA project.

Post Doctoral Researcher

Université Gustave Eiffel

Nov 2017 – Dec 2020 Lyon

Part of the ERC project Multiscale and Multimodal Traffic Modelling Approach for Sustainable Management of Urban Mobility (MAGnUM). Primary resposnbility is to develop the multi-modal macroscopic traffic simulators based on Macroscopic Fundamental Diagram (MFD).

Doctoral Researcher

Instituto Superior Técnico and Universitat Politècnica de Catalunya

Oct 2017 – Sep 2014 Lisbon and Barcelona

Primary contributions include proposing a novel coupling formulation between Continuous (CG) and Hybridizable discontinuous Galerkin (HDG) methods for thermo-fluid multi-physics problem. Developed an in-house arbitrary high-order solver in FORTRAN.

Research Intern

Compass Ingeniería y Sistemas

Jan 2013 – Jul 2013 Barcelona

The primary objective of the internship was to validate the in-house software SeaFEM, which is based on Finite Element Methods (FEM) to analyze the waves and currents in off-shore installations. The validation was done by comparing the Response Amplitude Operators (RAO) in the pitch motion of an off-shore wind turbine with the available data.

Research Assistant

Universität Stuttgart

May 2011 – Jul 2011 Stuttgart

A sensitivity analysis of the design variables of the Inertial Electrostatic Confinement (IEC) reactor was performed using metaheuristic optimization technique Simulated Annealing (SA).
