What I'm looking for

I aim to develop interdisciplinary teaching modules that integrate fluid dynamics, climate science, and machine learning.

At BIDR, Ben-Gurion University of the Negev, I research complex fluid instabilities and environmental fluid systems through CFD simulations, machine-learning-based image analysis, and experiments on multiphase flows in confined and porous media.

At IISER Mohali, I conducted numerical simulations of fluid instabilities and multiphase flows using COMSOL Multiphysics and MATLAB, with applications in optofluidics and interfacial transport. My work combines CFD-generated and experimental data with machine learning to develop predictive frameworks and identify underlying physical mechanisms.

I also developed reduced-order machine-learning models for flow prediction, including a hybrid POD–Random Forest model to reconstruct complex spatiotemporal flow fields while reducing computational cost. My research interests include transport phenomena, nonlinear instabilities, multiphase systems, and physics-informed computational modelling.
