Numerical simulation and stability analysis of interfacial flows: surfactant transport, Marangoni effects and interfacial instabilities.

About

I am a PhD candidate in interfacial fluid mechanics at IEMN (University of Lille), within the AIMAN-FILMS group, under the supervision of Prof. Michael Baudoin. My research focuses on high-fidelity numerical simulation and stability analysis of multiphase flows.

I develop research-level numerical methods for soluble and insoluble surfactant transport at fluid interfaces — coupled Volume-of-Fluid / Phase-Field schemes, adsorption-desorption kinetics and Marangoni effects — mainly using the open-source solver Basilisk. I am also interested in the linear stability analysis of two- and three-interface flows (multi-interface Navier-Stokes models, Helmholtz decomposition).

During my PhD I carried out research stays at IIT Bombay (Prof. Ratul Dasgupta) and IIT Roorkee (Prof. Palas Kumar Farsoiya), and presented my work at several international conferences. My PhD ends in October 2026: I am open to opportunities in computational fluid dynamics, interfacial flows and instability analysis.
