**About the Editors**

**Cinzia Tornatore** received a "Summa cum Laude" magister degree in chemical engineering in 2004 and PhD in 2007 from the University of Napoli Federico II. She is a tenured researcher at the Italian National Research Council (STEMS), where she has worked since 2004. Her work has been focused on the study of thermo-fluid dynamic processes that take place in internal combustion engines fueled with conventional and new-generation fuels. This research has been carried out mainly through the application of high-spatial- and -temporal-resolution optical techniques.

**Luca Marchitto** is a tenured researcher at the Italian National Research Council, where he has worked since 2007. His activity is mainly focused on the optimization of combustion processes in internal combustion engines and on the fluid dynamic characterization of sprays and air–fuel mixing in CI and SI engines by non-intrusive techniques.
