Born in 1992. I received my B.Sc. degree in Mechanical engineering (2014) and double M.Sc. degrees (2017) in Mathematical engineering, and in Technical Physics, specialization Advanced Computational Methods in Material Sciences. After M.Sc. graduation, I joined SISSA mathLab group (2017, Trieste) as a research fellow working on the project PRELICA: Advanced Methodologies for Hydro-acoustic Design of Naval Propulsion. In April 2023, I received my Ph.D. from Aalto University School of engineering in computational combustion physics. Presently, I work as Combustion and CFD Expert at Wärtsilä Finland Oy, as part of thermofluids and simulations team, working on engine combustion modeling and simulations.

I enjoy working on numerical modeling, numerical simulations, and scientific computing of various computational fluid dynamics problems. My research interests and previous experiences involve working on the following topics:
