Rodrigo Demarco, PhD

Research Interests

The research interests comprise energy conversion, heat and mass transfer in combustion, fluid dynamics, thermal radiation and soot production in flames, normal and inverse diffusion flames in normal and microgravity.

Vita

Rodrigo Demarco was born in Santiago de Chile. He obtained his Engineering and MSc degrees in mechanics at the University of Chile in 2008. Later he worked as a project engineer at the Mathematical Modeling in Mining and Metallurgy Lab (LM4) in the Center of Mathematical Modeling (CMM). In 2009 he was awarded with a mobility grant from the ALFA-Scientific Computing Advanced Training (SCAT) program joining the IUSTI in France. This grant allowed him to develop high accuracy spectral models to treat radiative heat transfer from flames. Afterwards he continue this line of research by doing his PhD with the financial support of the Institut de Radioprotection et de Sûreté Nucléaire (IRSN), France. In 2012 Dr. Demarco was awarded by CONICYT with the Integration Program of Advanced Human Capital in the Academy, integrating him as a research fellow at the Departamento de Industrias at the Universidad Técnica Federico Santa María (UTFSM), Chile. In 2015 he became Assistant Professor at UTFSM.
