Biography

Cristian joined Sandia in 2023 as a senior member of technical staff in the Plasma & Reacting Flows department. His research focuses on developing models and algorithms to mitigate the computational cost of high-fidelity, multi-physics simulations (in particular, turbulent reacting flows), often adopting a physics-based and/or data-based reduced-order modeling approach.
