Research interests
My main research interests involve the chemical kinetic analysis of reacting flows at different levels, including the development of kinetic mechanisms via first-principles and data-driven methodologies, as well as their subsequent reduction and optimization. The expertise that I gained during my academic career covers the pyrolysis and oxidation of fossil fuels and surrogates, mechanisms of formation of pollutant species (NOx, SOx), at a fundamental level as well as at real scales (turbulent combustion devices, e.g. furnaces and engines). In the context of decarbonization strategies for transportation and power generation, my most recent research efforts have focused on the kinetic modeling of the pyrolysis and oxidation of renewable energy carriers (specifically, ammonia, oxymethylene ethers).
During my career, my research has covered the following areas:
- Combustion instabilities
- Detailed kinetic mechanisms of pollutants formation (NOx, SOx, Soot)
- Chemistry of energy carriers
- Analysis and reduction of kinetic mechanisms
- Reactor network analysis
- Near-wall flame quenching
