Combustion, Thermofluids, Cardiff University.

Biography

I did my undergraduate studies in the UNAM, Mexico. After a 2 years post in the metal mechanical industry, I started a MSc and PhD in Energy and Combustion Technologies at Cardiff University, UK. In 2009, I went back to Mexico and worked in the research centre CIATEQ. Now, I´ve come back to the UK and joined Cardiff University as a Lecturer in Thermofluids and Combustion Science.
