Biography
I am passionate about understanding the complex behaviors of multiphase flows, with a particular focus on the rheology of particulate suspensions. My work explores how these materials move and interact under various conditions, which has broad applications across fields like material science, engineering, and fluid mechanics. Through advanced simulations and experiments, I strive to uncover the underlying physics that govern these systems, allowing for more accurate predictions and insights that can contribute to industrial processes, product design, and fundamental science. Recently, I started developing Machine Learning techniques for multiphase flows, both to predict the flow field from the geometry or to directly obtain rheological quantities from input parameters.

Other activities and projects related to teaching
During my PhD at Université Côte d'Azur (France), I've been teaching Calculus, Fluid Mechanics, and Physics to undergraduate students pursuing a Bachelor's Degree in Mathematics, Physics, and Biology. While I was a Research Associate at the City College of New York (USA), I've had the opportunity to have the full responsibility of the course Transport Phenomena for undergraduate students in Chemical and Biomedical Engineering.
