I received my Ph.D. in Fluid Mechanics from Institut Polytechnique de Paris (IP Paris) in January 2022. Immediately after, I joined the chair “AI and Aerodynamics” led by National Talent Prof. Dr. Bernd Rainer Noack as a postdoctoral fellow at Harbin Institute of Technology (Shenzhen), China.
I target an academic career focusing on automated reduced-order modeling (surrogate models) for digital twins, using flow data, machine learning, and first principles. The models will be employed for understanding, optimization, estimation, and control. The starting point is mean-field modeling, sparse identification, Galerkin force modeling, and cluster-based network modeling, which have been successfully applied to the benchmark configuration, “Fluidic Pinball.”
We tap the great potential of ROM synergizing machine learning techniques and first principles to meet the control and optimization requirements in complex industrial environments, addressing challenges of multi-scale and multi-frequency tasks.
Research interests:
Reduced-order modeling of complex systems using machine learning and first principles
Dimensionality reduction, feature extraction, and nonlinear modeling
Fluid dynamics, flow instabilities, and bifurcation theory

Reduced-order modelling and system identification can help us figure out the elementary degrees of freedom and the underlying mechanisms from the high-dimensional and nonlinear dynamics of fluid flow. Machine learning has brought new opportunities to these two processes and is revolutionising traditional methods. We focus on building a general framework to obtain a sparse human-interpretable model from complex high-dimensional data using machine learning and first principles.
