Staff Profile

I am a Research associate working at the MatCoRE group since January 2022, my research focuses on the development of ceramic-molten salt membranes for CO₂ separation.

I got a Chemistry degree from Universidad Nacional Autónoma de México (UNAM), studying the effect of a surface eutectic mixture on CO₂ capture alkaline materials. After that, I received MSc (Hons) (2015) and PhD’s degrees (2019) at the same University. During this time, I continued testing different alkaline materials as CO₂ captors but also get involved into dual phase molten carbonates-ceramic membranes for CO₂ separation. I also performed a research stay at the University of South Carolina during 2018 under the supervision of Prof. Kevin Huang, where I studied membrane reactors for methane dry reforming.

Before Newcastle I worked with Prof. John Irvine’s group at the University of Saint Andrews in 2020 as postdoctoral researcher where I studied the design of an electrochemical membrane reactor system to produce NH₃ from H₂ and N₂.

I am specially interested on solid state chemistry and its application on energy-related devices, such as gas separation membranes or fuel cells.
